Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a data processing method, device and computer-readable medium. Background Art

[0002] In JavaScript, container data is nested data, which is also called reference type data, such as object type data and array type data. Currently, there are two ways to modify reference type data.

[0003] The first method is that when the internal attributes or elements of the reference type data are modified, the value of the reference type data itself will not change. For example, for nested data A, after the E value corresponding to Key4 in A.Key1.Key4 is changed to F, the only change in the entire nested data A is the change in the value of Key4, while other locations, such as the attribute values corresponding to the outer layer A of the nested data and the key1 key in A, have not changed. Therefore, this method cannot be used to observe whether the nested data A has changed from the value of the outer layer A of the nested data, and then it is difficult to collect its change history. The second method is the immutable data body technology, which first declares the variable of the immutable data body, and then modifies the nested data in the variable, such as assigning a key value to an object in the nested data, deleting a key of the object, adding a key-value pair of the object, assigning or deleting an element at a certain position in the array, or increasing or decreasing the number of elements in the array, etc. Since these modification, addition, and deletion operations will result in a new data body being generated, for example, after the value of E corresponding to Key4 in A.Key1.Key4 is changed to F, E in the returned result is replaced by F; since E is the value inside the attribute value (object B) corresponding to Key1 in object A, the object B in the returned result is replaced by the new object B'; similarly, the change in object B causes object A to be replaced by the new object A'. In this immutable data body technology, the unchanged part still uses the original value. Although this method can infer changes to the nested data A from the value of the outer layer A of the nested data, it is still difficult to collect its change history.

[0004] In the prior art, if developers need to collect the change history of such nested data, the general method is to obtain a historical snapshot by deeply copying the nested data before and after it is changed, and then use the tree data deep traversal comparison method to calculate the difference, thereby obtaining the data change history. Therefore, the existing data change history collection, whether facing immutable data or conventional reference type data, is mainly through the deep traversal comparison method. Both of the above methods require the use of the before-and-after snapshot comparison method, which will cause a large memory usage; in addition, when performing deep traversal comparison, it will also consume a lot of computing time and resources. Summary of the Invention

[0005] The present invention provides a data processing method, apparatus and computer-readable medium. This method can directly and effectively collect the change results of reference type data without executing any algorithms, solves the problems of large consumption of calculation time and resource occupation caused by calculating differences using the deep traversal comparison method in the prior art, and reduces the calculation amount in the process of collecting change history.

[0006] To achieve the above object, according to the first aspect of the embodiments of the present application, a data processing method is provided. Specifically, a corresponding first proxy object is created for the target data, where the target data is a container data of reference type; an attribute trigger instruction for the first proxy object is obtained; in response to the attribute trigger instruction, an operation corresponding to the attribute trigger instruction is performed on the target data to generate a historical operation record.

[0007] Optionally, creating a corresponding first proxy object for the target data includes: determining whether a first proxy object corresponding to the target data exists in the cache area; if not, a corresponding first proxy object is created for the target data based on the target data and the attribute operation interface corresponding to the target data.

[0008] Optionally, if the attribute trigger instruction is used to indicate intercepting the access attribute operation of the target data through the first proxy object; performing an operation corresponding to the attribute trigger instruction on the target data to generate a historical operation record includes: obtaining the access path of the target data; accessing the attribute of the target data based on the access path to obtain an attribute value; if the attribute value is an object, a corresponding second proxy object is created for the attribute value; an access operation record is generated based on the parent-child relationship between the first proxy object and the second proxy object and the access path.

[0009] Optionally, if the attribute trigger instruction is used to indicate intercepting the current change attribute operation of the target data through the first proxy object; the attribute operation instruction includes the current change attribute and the change path; performing an operation corresponding to the attribute trigger instruction on the target data to generate a historical operation record includes: using the current change attribute as a child node, obtaining the parent node corresponding to the child node from the target data; determining whether the change path exists in the parent node; based on the determination result, determining the current change attribute operation intercepted by the first proxy object to generate a change operation record.

[0010] Optionally, when the attribute operation instruction further includes the new value corresponding to the currently modified attribute; based on the judgment result, determining the currently modified attribute operation intercepted by the first proxy object, and generating a modification operation record, including: if the judgment result indicates that the parent node has the modification path, determining that the currently modified attribute operation intercepted by the first proxy object is an assignment operation, and obtaining the old value corresponding to the child node from the target data; generating an assignment operation record based on the parent node, the modification path, and the new value and the old value corresponding to the child node; if the judgment result indicates that the parent node does not have the modification path, determining that the currently modified attribute operation intercepted by the first proxy object is an addition operation; generating an addition operation record based on the parent node, the modification path, and the new value corresponding to the child node.

[0011] Optionally, when the attribute operation instruction does not include the new value corresponding to the currently modified attribute; based on the judgment result, determining the currently modified attribute operation intercepted by the first proxy object, and generating a modification operation record, including: if the judgment result indicates that the parent node has the modification path and the modification path can be deleted, determining that the currently modified attribute operation intercepted by the first proxy object is a deletion operation; generating a deletion operation record based on the parent node, the modification path, and the child node.

[0012] Optionally, the method further includes: obtaining a modification path request starting from the target data for the currently modified attribute; querying, based on the modification path request, the parent node corresponding to the currently modified attribute from the modification operation record; using the parent node as the currently queried child node, and querying the parent node corresponding to the currently modified attribute from the access operation record; repeating the above query operation until the parent node is the target data, then ending the query operation and generating a new modification operation record.

[0013] To achieve the above object, according to a second aspect of the embodiments of the present application, a data processing device is provided.

[0029] To make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0030] As Figure 1 shown, it is a structural schematic diagram of modifying reference type data by using the first method in the prior art. The outermost layer of the nested data A is the object A; inside the object A, there are the Key1 key and the Key2 key, where the attribute value corresponding to the Key1 key is the object B, and the attribute value corresponding to the Key2 key is C; inside the object B, there are the Key3 key and the Key4 key, where the attribute value corresponding to the Key3 key is D, and the attribute value corresponding to the Key4 key is E. After performing an assignment operation on the nested data A, that is, modifying the E value corresponding to the Key4 key inside the nested data A to the F value, there is no change in the outermost object A of the nested data A. Therefore, it is difficult to observe the internal changes through the outermost layer of the nested data A.

[0031] As Figure 2 shown, it is a structural schematic diagram of modifying reference type data by using the second method in the prior art.

[0032] The outermost layer of the nested data A is the object A; inside the object A, there are the keys Key1 and Key2. The property value corresponding to the key Key1 is the object B, and the property value corresponding to the key Key2 is C; inside the object B, there are the keys Key3 and Key4. The property value corresponding to the key Key3 is D, and the property value corresponding to the key Key4 is E. Based on the immutable data body technology, an assignment operation is performed on the nested data A, that is, the value E corresponding to the key Key4 inside the nested data A is modified to the value F. The value E is the property value of the object B. Since the value E has changed, the object B in the return result is replaced with the object B'; the object B is the property value of the object A. Since the object B has changed, the object A in the return result is replaced with the new object A'. The unchanged parts in the nested data A still use the original values, such as Figure 2 the property values D and C in.

[0033] As Figure 3 shown, it is a schematic flowchart of the data processing method provided by an embodiment of the present invention; as Figure 7 shown, it is a schematic structural diagram of creating a first proxy object for the target data in an embodiment of the present invention. A data processing method at least includes the following steps: S301, creating a corresponding first proxy object for the target data, where the target data is a container data of reference type; S302, obtaining an attribute trigger instruction for the first proxy object; S303, in response to the attribute trigger instruction, performing an operation corresponding to the attribute trigger instruction on the target data to generate a historical operation record.

[0034] In S301, the container data of reference type is also called nested data.

[0035] By controlling the createReactivity function, using the characteristics of JavaScript's Proxy to create a first proxy object for the target data, and the first proxy object is used to intercept the basic operations of the target data. The basic operations can be operations such as access, assignment, addition, or deletion. For example, creating a first proxy object A' for the outermost object A of the target data to obtain a proxy relationship mapping, as Figure 7 shown.

[0036] In 302 and S303, when the attribute trigger instruction is used to indicate intercepting the access attribute operation of the target data through the first proxy object, in response to this attribute trigger instruction, an access operation is performed on the current attribute inside the target data to generate an access operation record.

[0037] When the attribute trigger instruction is used to indicate intercepting the assignment operation of the current modified attribute of the target data through the first proxy object; in response to this attribute trigger instruction, an assignment operation is performed on the current modified attribute inside the target data to generate an assignment operation record.

[0038] When the attribute trigger instruction is used to indicate intercepting the addition operation of the currently modified attribute of the target data through the first proxy object; in response to the attribute trigger instruction, an addition operation is performed on the currently modified attribute inside the target data, and an addition operation record is generated.

[0039] When the attribute trigger instruction is used to indicate intercepting the deletion operation of the currently modified attribute of the target data through the first proxy object; in response to the attribute trigger instruction, a deletion operation is performed on the currently modified attribute inside the target data, and a deletion operation record is generated.

[0040] In a preferred implementation manner of the first embodiment, creating a corresponding first proxy object for the target data includes: determining whether there is a first proxy object corresponding to the target data in the cache area; if not, creating a corresponding first proxy object for the target data based on the target data and the attribute operation interface corresponding to the target data.

[0041] Specifically, first initialize the buffer area corresponding to the target data. The initialized buffer area is used to store the proxy object of the target data and the historical operation records; then determine whether the parameter passed into the createReactivity function belongs to the reference type to obtain a first judgment result; if the first judgment result indicates that the parameter is not of the reference type, an error prompt is given; if the first judgment result indicates that the parameter is of the reference type, then continue to determine whether the parameter is the first proxy object that has been processed by the createReactivity function and corresponds to the target data to obtain a second judgment result; if the second judgment result indicates that the parameter is the first proxy object that has been processed by the createReactivity function and corresponds to the target data, then directly return the first proxy object; if the second judgment result indicates that the parameter is not the first proxy object that has been processed by the createReactivity function and corresponds to the target data, then determine whether there is a first proxy object corresponding to the target data in the cache area; if not, create a corresponding first proxy object for the target data based on the target data and the internal attribute operation interface corresponding to the target data. Here, the attribute operation interface is used to indicate multiple attribute interception methods inside the target data.

[0042] The method of the embodiment of the present invention first creates a corresponding first proxy object for the target data, where the target data is a container data of reference type; then obtains an attribute trigger instruction for the first proxy object; and finally, in response to the attribute trigger instruction, performs an operation corresponding to the attribute trigger instruction on the target data to generate a historical operation record. Thus, without post-computation, the change history of reference type data can be effectively collected, solving the problems in the prior art that due to the later use of the deep traversal and comparison method to calculate the differences between the reference type data before and after the change, the computational time cost is large and the memory resources are wasted during the change history collection process, and reducing the computational amount in the change history collection process.

[0043] In another preferred embodiment of this embodiment, as Figure 4 shown, it is a schematic flowchart of generating an access operation record in an embodiment of the present invention; as Figure 8 shown, it is Figure 4 a schematic structural diagram of the internal access path and access operation record of the target data in

[0044] If the attribute trigger instruction is used to indicate intercepting the access attribute operation of the target data through the first proxy object; performing an operation corresponding to the attribute trigger instruction on the target data to generate a historical operation record, at least including the following steps: S401, obtaining the access path of the target data; S402, accessing the attribute of the target data based on the access path to obtain the attribute value; S403, if the attribute value is an object, creating a corresponding second proxy object for the attribute value; S404, generating an access operation record based on the parent-child relationship between the first proxy object and the second proxy object and the access path.

[0045] Specifically, if the target data is an object or an array, then use the Reflect.get function to access the attributes of the target data with native semantics to obtain the attribute value; if the attribute value is not an object, return the value; if the attribute value is an object, then use the createReactivity function to process the value to obtain the second proxy object corresponding to the target data; finally, record the parent-child relationship between the first proxy object and the second proxy object and the access path in the cache area to generate an access operation record. If the target data is an array and the attribute accessed for the target data belongs to a method on the array prototype chain, such as push, pop, slice, indexOf, etc., then obtain the corresponding method from the target data.

[0046] For example, for the nested data A, the first proxy object A' can be obtained after being processed by the createReactivity function. When intercepting the access attribute operation of the nested data A through the first proxy object A', if accessing the attribute of the nested data A based on the access path Key1, and the obtained attribute value is the object B. Since this attribute value is an object, a corresponding second proxy object B' is created for this attribute value. Based on the parent-child relationship between the first proxy object A' and the second proxy object B' and the access path Key1, an access operation record is generated, that is, a parent-child relationship record, such as Figure 8 as shown; and this access operation record is stored in the cache area.

[0047] If accessing the attribute of the nested data A based on the access path Key2, and the obtained attribute value is C. Since C is not an object, the original value can be directly returned. Based on the parent-child relationship between the first proxy object A' and the attribute value C and the access path Key2, another access operation record is generated; similarly, this access operation record is stored in the cache area.

[0048] Thus, it is possible to intercept the access operation inside the target data through the first proxy object, so that the access operation record of the target data can be effectively obtained.

[0049] In another preferred embodiment of this embodiment, if the attribute trigger instruction is used to indicate intercepting the current modified attribute operation of the target data through the first proxy object; the attribute operation instruction includes the current modified attribute and the modification path; performing an operation corresponding to the attribute trigger instruction on the target data to generate a historical operation record, which at least includes the following steps: using the current modified attribute as a child node, obtaining the corresponding parent node from the target data; judging whether the modification path exists in the parent node; based on the judgment result, determining the current modified attribute operation intercepted by the first proxy object, and generating a modification operation record.

[0050] As Figure 5 shown, it is a schematic flowchart of generating an assignment operation record and an addition operation record in an embodiment of the present invention; as Figure 9 shown, it is Figure 5 a schematic structural diagram of the internal modification path of the target data and the assignment operation record as shown.

[0051] In a preferred embodiment, if the attribute trigger instruction is used to indicate intercepting the current modified attribute operation of the target data through the first proxy object; the attribute operation instruction includes the current modified attribute and the modification path; performing an operation corresponding to the attribute trigger instruction on the target data to generate a historical operation record, including at least the following steps: S501, taking the current modified attribute as a child node, and obtaining the parent node corresponding to the child node from the target data; S502, determining whether the parent node has a modification path; S503, if the determination result indicates that the parent node has a modification path, determining that the current modified attribute operation intercepted by the first proxy object is an assignment operation, and obtaining the old value corresponding to the child node from the target data; generating an assignment operation record based on the parent node, the modification path, and the new value and the old value corresponding to the child node; S504, if the determination result indicates that the parent node does not have a modification path, determining that the current modified attribute operation intercepted by the first proxy object is an addition operation; generating an addition operation record based on the parent node, the modification path, and the new value corresponding to the child node.

[0052] Specifically, when the target data is an array, if the attribute key corresponding to the parent node in the array is a number and the size of the number is less than the length of the array, it is determined that the parent node in the array has the modification path, then the current modified attribute operation intercepted by the first proxy object is an assignment operation; otherwise, it is determined that the parent node in the array does not have the modification path, then the current modified attribute operation intercepted by the first proxy object is an addition operation.

[0053] When the target data is an object, if the parent node in the object has the modification path, it is determined that the parent node has the modification path, then the current modified attribute operation intercepted by the first proxy object is an assignment operation; otherwise, it is determined that the parent node in the object does not have the modification path, then the current modified attribute operation intercepted by the first proxy object is an addition operation.

[0054] After that, the target data is accessed through the first proxy object to obtain the old value corresponding to the child node. The finally generated assignment operation record and addition operation record are both stored in the cache area.

[0055] For example: performing an assignment operation on the nested data A, making it the second proxy object B'.Key4 = F. Then the above assignment interception logic will replace E in the original unproxied object A with F, and record the modification history. The generated modification history record is as Figure 9 shown.

[0056] Thus, through the first proxy object, the assignment operation or addition operation inside the target data can be intercepted, so that the assignment operation record or addition operation record of the target data can be effectively obtained.

[0057] Such as Figure 6As shown, it is a schematic flowchart of generating a deletion operation record in an embodiment of the present invention; as Figure 10 shown, it is Figure 6 a schematic structural diagram of the internal change path of the target data and the deletion operation record as shown.

[0058] In a preferred embodiment, if the attribute trigger instruction is used to indicate intercepting the current change attribute operation of the target data through the first proxy object; the attribute operation instruction includes the current change attribute and the change path; performing an operation corresponding to the attribute trigger instruction on the target data to generate a historical operation record, which at least includes the following steps: S601, taking the current change attribute as a child node, and obtaining the parent node corresponding to the child node from the target data; S602, determining whether the parent node has a change path; S603, if the judgment result indicates that the parent node has a change path and the change path can be deleted, determining that the current attribute operation intercepted by the first proxy object is a deletion operation; generating a deletion operation record based on the parent node, the change path, and the child node; S604, if the judgment result indicates that the parent node does not have a change path or has a change path but the change path cannot be deleted, determining that the current attribute operation intercepted by the first proxy object cannot be executed.

[0059] For example, if the parent node does not have a change path, the deletion operation is performed according to the native semantics, and no deletion operation record is generated; if the parent node has a change path, but the parent node is frozen or the change path of the parent node cannot be deleted, the current operation cannot be executed.

[0060] For example, when deleting B'.Key4 of the second proxy object, the above-mentioned deletion operation interception logic will delete E in the original un-proxied object A and record the change history, and the generated change history record is as Figure 10 shown.

[0061] Thus, through the first proxy object, the deletion operation inside the target data can be intercepted, so that the deletion operation record of the target data can be effectively obtained.

[0062] In another preferred embodiment of the present invention, the data processing method further includes the following operation steps: for the current change attribute, obtaining a change path request starting from the target data; based on the change path request, querying the parent node corresponding to the current change attribute from the change operation record; taking the parent node as the current queried child node, and querying the parent node corresponding to the current change attribute from the access operation record; repeating the above query operation until the queried parent node is the target data, then ending the query operation and generating a new change operation record.

[0063] Specifically, in the usage phase, this solution will provide a function named produce to accept data changes. This function takes a callback as a parameter. Inside this callback, the business side can perform corresponding operations using assignment and deletion operation writing methods that are no different from the general writing methods.

[0064] The following steps will be executed inside this produce function: clear the above-mentioned array used for change history records; execute the callback parameter; and return the above-mentioned array used for change history records as the return value. The data change operations in the callback function will trigger the above-mentioned property interception. Then the business side can obtain the historical operation records from the return value of the produce function.

[0065] Thus, for any current changed property in the change operation record, an access path starting from the top layer of the target data can be queried from the access operation record, so as to obtain a more complete change operation record, improve the efficiency of collecting the change history of the target data, reduce the unnecessary resource occupation in the traditional method, and improve the data processing speed.

[0066] It should be understood that in various embodiments of the present invention, the magnitudes of the sequence numbers of the above-mentioned processes do not mean the order of execution. The execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
