[0040] Before describing in detail the message transmission system and the message transmission method provided by the following embodiments of the present invention, the related concepts involved in the following embodiments may be explained first:

[0041] LiveData is a data holding container class with lifecycle awareness, which can also be called a data storage component. LiveData implements the observer pattern, which allows registered observers to receive notifications when messages change. Observers include components that need to receive message updates, such as Activity components or Fragment components in applications.

[0042] Generics are a feature in programming languages ​​that allow developers to write code without specifying a specific type, but instead use a placeholder (called a type parameter) to represent any type. <t>express.

[0043] A generic class is a class defined using generic features. The LiveData mentioned above is essentially a generic class that can store message objects of any type. For example, LiveData <user>Indicates that the message object of type User is stored, LiveData <message>Indicates that the message object stored is of the Message type.

[0044] Before describing in detail the message transmission system and the message transmission method provided by each embodiment of the present invention, an application scenario of message transmission may be schematically described:

[0045] As described in the background technology, in order to ensure that the application can run efficiently, messages can be transmitted between components. Among them, the components in the application can include core components such as Activity or Fragment for building a user interface. Among them, the Fragment component can be a part of the Activity component, and it can also be regarded as a subcomponent of the Activity.

[0046] In practical applications, messages transmitted between different components can usually be transmitted with the help of different transmission channels provided by the message bus, and different channels can be used to transmit different types of messages.

[0047] For example, the message bus can add different string identifiers for different types of messages, and use the string identifiers as channel identifiers to distinguish different message channels. However, if the string identifier is added incorrectly, the message will not be sent to the correct message channel, and when the number of message channels is large, it will become more difficult to use string identifiers to distinguish message channels. Therefore, it is easy to cause the message to be mistakenly sent to an incorrect channel due to channel identification errors, thereby reducing the accuracy of message transmission. In order to improve the above problems, the message transmission system and message transmission method provided by the following embodiments of the present invention can be used.

[0048] It should be noted that this solution does not limit the scenario for message transmission, and the message transmission between components in the above application is only an illustration.

[0049] Based on the above description, some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the case where there is no conflict between the embodiments, the following embodiments and the features in the embodiments can be combined with each other. In addition, the step sequence in the following method embodiments is only an example and not a strict limitation.

[0050] Figure 1 The structure diagram of a message transmission system provided by an embodiment of the present invention is shown in FIG. 1 , and the message transmission system can be deployed in an application program. Figure 1 As shown, the message transmission system includes a message bus, a message processing component, a data storage component, a first component as a publisher, and a second component as a subscriber.

[0051] Before describing in detail the specific working process of each part of the message transmission system provided by the embodiment of the present invention, the overall working process of the message transmission system may also be described first:

[0052] In practical applications, the message bus can provide functions of publishing messages and subscribing messages. Then, the first component as a publisher can first generate a first message object encapsulating a first class instance, and publish the first message object to the message bus.

[0053] Then, the message processing component can execute the inline function to identify the first class identifier of the first class instance. Then, the message bus can determine whether there is a message channel corresponding to the first class identifier in itself. If there is no message channel corresponding to the first class identifier in the message bus, the message bus can use the first class identifier as a channel identifier, create a first message channel corresponding to the first class identifier, and store the first message object in a data storage component corresponding to the first message channel. Optionally, the data storage component can be included in the message bus.

[0054] Finally, the second component can use the first message channel to obtain the first message object from the data storage component corresponding to the first message channel to implement message transmission between the first component and the second component.

[0055] The specific working process of the first component publishing messages to the message bus can be combined with Figure 2 Optionally, the first component as the publisher may include the Activity component or Fragment component mentioned above.

[0056] Specifically, if Figure 2 As shown, the first component can first determine the first declaration information, and create a first class instance with the first class identifier according to the first class identifier in the first declaration information. The first declaration information includes a class that defines the properties and methods of the message. The first class instance refers to a specific instance created according to the first class identifier in the first declaration information, that is, the specific message content that the first component wants to pass to the second component, which can implement the properties and methods of the message defined in the first declaration information.

[0057] Next, the first component can generate a first message object encapsulating the first class instance according to the preset message format. After that, the first component can call a message sending method (such as setValue( <t>) method) to send the first message object to the message bus. Optionally, the message sending method includes a generic method, wherein, <t>It can generally refer to the type parameter of the first message object.

[0058] Optionally, different declaration information may include different class identifiers, and different class identifiers may correspond to different Class types. Class type refers to a data type defined by the Class keyword, which may specifically include a User type for representing a publisher type or a Message type for representing a message type, and the like.

[0059] The message processing component can execute the inline function included in itself to <t>, identifying the first class identifier of the first class instance. Optionally, the message processing component may specifically include a Kotlin compiler.

[0060] The message bus may first obtain the first message object. Then, the message bus may determine whether there is a message channel corresponding to the first type of identifier in the message bus. If there is no message channel corresponding to the first type of identifier in the message bus, the message bus may use the first type of identifier as a channel identifier to create a first message channel corresponding to the first type of identifier. Afterwards, the message bus may store the first message object it obtains in the data storage component corresponding to the first message channel.

[0061] Optionally, a message channel may correspond to a data storage component, and a data storage component is used to store a message object. Optionally, the data storage component may specifically include a LiveData component.

[0062] In actual applications, optionally, in addition to the storage function, the data storage component may also have a message update notification function. Specifically, the storage component may send a message update notification to the second component in response to the storage of the first message object. Among them, the second component is the component that needs to receive the message update. Then, in response to the reception of the message update notification, the second component may use the first message channel to obtain the first message object from the data storage component corresponding to the first message channel, thereby realizing the message transmission between the first component and the second component. Optionally, the second component as a subscriber may also include the Activity component or Fragment component mentioned above.

[0063] In this embodiment, the first class identifier of the first class instance itself is first identified by means of the message processing component, and then the first class identifier is directly used as the channel identifier through the message bus, and finally the message object can be transmitted from the message channel with this channel identifier. Compared with the scheme of first extracting the string identifier from the class instance, then adding the string identifier to the class instance, and using the string identifier as the channel identifier, the message processing component in this scheme can more easily and accurately extract the class identifier from the class instance, so as to ensure that the message object can be transmitted on the correct channel, avoiding the problem of the message object being transmitted on the wrong channel due to the non-standard string identifier, thereby improving the accuracy of message transmission.

[0064] It should be noted that in actual applications, the message bus may receive message objects sent by multiple components as publishers at the same time. In this case, the message processing component can identify the class identifiers of different class instances contained in different message objects by executing inline functions. Furthermore, the message bus can create different message channels according to different class identifiers.

[0065] For example, if Figure 3 As shown, the component as publisher 1, the component as publisher 2, the component as subscriber 1, and the component as subscriber 2 can communicate through the message bus without directly establishing contact. Optionally, the message bus can use a mapping (MAP) set to store the mapping relationship between the name of the message channel (such as message channel 1, message channel 2, or message channel N, etc.) and the data storage component. Among them, the name of the message channel corresponds to the class identifier of the class instance.

[0066] Above Figure 1 The first component mentioned in the illustrated embodiment is in the publishing stage. In practical applications, before publishing a message, the first component may also be in the registration stage. Specifically, the message bus may obtain a registration event generated by the first component to register the first component. Optionally, the message bus may include a registration center, which may be used to manage components that publish and subscribe to messages. After obtaining the registration event generated by the first component, the message bus may register the first component in the registration center.

[0067] Regarding the generation of the registration event, specifically, the first component may obtain component information, and generate a registration event according to the component information. Optionally, the component information may include the name of the component, a component identifier for distinguishing different components, an intent filter, etc. Among them, the intent filter can be understood as a set of rules that define the type of message objects that the first component can respond to.

[0068] In this embodiment, by registering the first component in the message bus, the message bus can better manage the component that publishes the message, that is, the first component, to ensure the consistency and reliability of message transmission.

[0069] According to the above Figure 1-2 As can be seen from the description in the illustrated embodiment, the first component needs to generate a first message object first, and then send the first message object to the message bus. Also, before the first component publishes a message, the first component needs to send a registration event generated by itself to the message bus.

[0070] Based on this, the first target object can be processed by means of the message processing component to reduce the sending operation of the first component. The first target object includes the above-mentioned registration event and / or the first message object.

[0071] Specifically, the message processing component can execute the extension function contained in itself to add the second class instance to the first target object. Then, the message processing component can execute the second class instance to automatically send the first target object to the message bus.

[0072] Among them, the extension function provides a flexible way to add a new class instance to an existing target object without modifying the target object, so that developers can easily extend the functionality of the target object without destroying the structure of the existing target object.

[0073] In this embodiment, with the help of a message processing component, a second type instance is added to the first target object generated by the first component, and the second type instance is executed, so that the first target object can be automatically sent to the message bus, reducing the sending operation of the first component, thereby improving the efficiency of message transmission.

[0074] In the above embodiments, it has been mentioned that the second component can use the first message channel to directly obtain the first message object from the data storage component corresponding to the first message channel. In actual applications, there may also be a situation where the first component may not have published the message to the message bus, that is, the message channel has not been established in the message bus, so that the second component cannot directly obtain the message it wants to obtain from the message bus.

[0075] The second component can first subscribe to the message from the message bus, and then transmit the message to the second component after the message bus obtains the message. Figure 4 understand.

[0076] Specifically, if Figure 4 As shown, the second component can first determine the second declaration information, and create a third type instance with the second type identifier according to the second type identifier in the second declaration information. The second type instance refers to a specific instance created according to the second type identifier in the second declaration information, that is, the specific message content that the second component wants to subscribe to, which can implement the properties and methods of the message defined in the second declaration information.

[0077] Then, the second component can generate a second message object encapsulating the third class instance according to the preset format. After that, the second component can call the message receiving method (such as observe( <t>) method), to send the second message object to the message bus, that is, to complete the subscription of the second message object. Optionally, the message receiving method includes a generic method, wherein, <t>It can generally refer to the type parameter of the second message object.

[0078] The message processing component can execute the inline function contained in it to receive the second message object according to the type parameter passed in the message receiving method. <t>, identifying the second type of identifier of the third type of instance. The second type of identifier is different from the first type of identifier, that is, the Class type corresponding to the second type of identifier is different from the Class type corresponding to the first type of identifier.

[0079] The message bus may first obtain the second message object. Then, the message bus may determine whether there is a message channel corresponding to the second type of identifier in the message bus. If there is no message channel corresponding to the second type of identifier in the message bus, the message bus may use the second type of identifier as a channel identifier and create a second message channel corresponding to the second type of identifier.

[0080] Afterwards, if the message bus determines that the third class instance contained in the third message object sent by the first component has the second class identifier, the third message object can be stored in the data storage component corresponding to the second message channel. The second message channel corresponds to the second class identifier. In other words, the data storage component corresponding to the second message channel can store the third message object generated by the first component, and the third message object includes the third class instance with the second class identifier.

[0081] And the data storage component can send a message update notification to the second component in response to the storage of the third message object. Then the second component can obtain the third message object from the data storage component using the second message channel in response to the reception of the message update notification. The third message object and the second message object each contain the same message content, that is, the message transmission is realized between the first component and the second component.

[0082] In this embodiment, the second type identifier of the third type instance itself is first identified by means of the message processing component, and then the second type identifier is directly used as the channel identifier through the message bus, so that the second component can first subscribe to the second message object from the message bus, until the subsequent message bus obtains the third message object published by the first component, and then uses the message channel with this channel identifier to transmit the third message object to the second component. Since the second message object and the third message object each contain the same message content, the normal transmission of messages between the first component and the second component can be guaranteed.

[0083] And compared to the solution of first extracting the string identifier from the class instance, then adding an additional string identifier to the class instance, and using the string identifier as the channel identifier, the message processing component in this solution can extract the class identifier from the class instance more easily and accurately, thereby ensuring that the message object can be transmitted on the correct channel, avoiding the problem of message objects being transmitted on the wrong channel due to non-standard string identifiers, thereby improving the accuracy of message transmission.

[0084] Above Figure 4 The second component mentioned in the illustrated embodiment is in the subscription stage. In practical applications, before subscribing to the message object, the second component may also be in the registration stage. Specifically, the message bus may obtain the registration event generated by the second component to register the second component. Optionally, after obtaining the registration event generated by the second component, the message bus may register the second component in the registration center.

[0085] Regarding the generation of the registration event, specifically, the second component can obtain component information and generate a registration event based on the component information. Optionally, the component information can also include the name of the component, a component identifier for distinguishing different components, an intent filter, etc. The specific process can refer to the registration process of the first component above, which will not be repeated here.

[0086] In this embodiment, by registering the second component in the message bus, the message bus can better manage the component that subscribes to the message, that is, the second component, to ensure the consistency and reliability of message delivery.

[0087] And according to the above Figure 4 As can be seen from the description of the illustrated embodiment, the second component needs to generate the second message object first, and then send the second message object to the message bus. And before the second component subscribes to the message, the second component also needs to send the registration event generated by itself to the message bus.

[0088] Based on this, the second target object can be processed by means of the message processing component to reduce the sending operation of the second component. The second target object includes the above-mentioned registration event and / or the second message object.

[0089] Specifically, the message processing component can execute the extension function contained in itself to add the fourth class instance to the second target object. Then, the message processing component can execute the fourth class instance to automatically send the second target object to the message bus.

[0090] In this embodiment, with the help of the message processing component, a fourth type instance is added to the second target object generated by the second component, and the fourth type instance is executed, so that the second target object can be automatically sent to the message bus, reducing the sending operation of the second component, thereby further improving the efficiency of message transmission.

[0091] The above is a description of the message transmission process from the perspective of the system. In addition, the message transmission process can also be described from the perspective of a message bus integrator. The message bus integrator includes the message processing components and the message bus mentioned above.

[0092] but Figure 5 A flowchart of a message transmission method provided by an embodiment of the present invention. The message transmission method provided by an embodiment of the present invention can be executed by the message bus integrator. It can be understood that the message bus integrator can be implemented as software, or a combination of software and hardware. Optionally, the message bus integrator can be deployed in an application. And a first component as a publisher and a second component as a subscriber can also be deployed in the application. Then Figure 5 As shown, the method comprises the following steps:

[0093] 501. Obtain a message object encapsulating a class instance, where the class instance is created by the first component according to the class identifier in the declaration information.

[0094] 502 , executing an inline function in a message bus integrator to identify a class identifier of a class instance.

[0095] 503. If the message channel corresponding to the class identifier does not exist, the class identifier is used as the channel identifier to create a message channel corresponding to the class identifier.

[0096] 504, store the message object in a data storage component corresponding to the message channel, so that the second component can obtain the message object from the data storage component using the message channel, and the data storage component is included in the message bus integrator.

[0097] The message bus integrator may first obtain a message object encapsulating a class instance. The class instance may be pre-created by the first component according to the class identifier in the declaration information. The specific creation process may refer to the above Figure 1 Description of the illustrated embodiment.

[0098] Then, the message bus integrator can execute the inline function contained in itself to identify the class identifier of the class instance. Then, the message bus integrator can determine whether there is a message channel corresponding to the class identifier in itself. If there is no message channel corresponding to the class identifier in the message bus, the message bus can use the class identifier as the channel identifier to create a message channel corresponding to the class identifier.

[0099] Afterwards, the message bus integrator can store the message object in the data storage component corresponding to the message channel, so that the second component can use the message channel to obtain the message object from the data storage component corresponding to the message channel, thereby realizing the message transmission between the first component and the second component. Among them, the data storage component is included in the message bus integrator, which can specifically include a LiveData component. Optionally, one message channel can correspond to one data storage component.

[0100] In this embodiment, the class identifier of the class instance itself can be first identified by the message bus integrator, and then the class identifier is directly used as the channel identifier, so that the message object can be transmitted from the message channel with the channel identifier. Compared with the solution of first extracting the string identifier from the class instance, then adding the string identifier to the class instance, and using the string identifier as the channel identifier, this solution can more easily and accurately extract the class identifier from the class instance, so as to ensure that the message object can be transmitted on the correct channel, avoiding the problem of the message object being transmitted on the wrong channel due to the non-standard string identifier, thereby improving the accuracy of message transmission.

[0101] In addition, the contents not described in detail in this embodiment and the technical effects that can be achieved can also be referred to in Figure 1 The embodiments shown will not be described in detail here.

[0102] The message transmission device of one or more embodiments of the present invention will be described in detail below. Those skilled in the art will appreciate that these message transmission devices can be configured using commercially available hardware components through the steps taught in this solution.

[0103] Figure 6 A schematic diagram of a message transmission device provided by an embodiment of the present invention is shown in FIG. Figure 6 As shown, the device comprises:

[0104] The acquisition module 11 is used to acquire a message object encapsulating a class instance, where the class instance is created by the first component according to the class identifier in the declaration information.
