Problems solved by technology

[0004] When tracking attribute changes, due to the possibility of attribute duplication, different code locations use the same attribute value. In this case, it may be difficult to accurately locate the context of attribute changes if the process of simply outputting attribute changes

example 2

[0075]

[0076] For example, object instance 1 and object instance 2 above, if there are different instances of the same object class (class), there will be different attribute values ​​in most cases, such as the OrderID of object instance 1 and object instance 2 above (object instance 1 and object instance 2). identification of instance 2).

[0077] When the data tracking recorder is instantiated outside the object instance 1 and the object instance 2 to track the changes of the key property IsSupportBookSeat of the object instance 1 and the object instance 2, the OrderID of the object instance 1 and the object instance 2 can be used as an associated property, when When the key attribute IsSupportBookSeat changes, the OrderID is also recorded in the data tracking recorder.

[0078] In this case, when the values ​​of the key attributes of object instance 1 and object instance 2 change at the same time, since the different values ​​of the object instances (or the id...

Abstract

The invention provides an object instance key attribute and related attribute tracking method and device. An object instance comprises multiple attributes, the multiple attributes includes at least one key attribute and at least one related attribute, and the value change of the key attribute is caused by the value change of at least one related attribute. The tracking method includes the steps that a data tracking recorder is generated and initialized; when the key attribute is assigned so that the value of the key attribute can change, the data tracking recorder records the current value of the key attribute, the current value of the related attribute and one location identification, and the location identification represents the code segment location with the key attribute assigned. The object instance key attribute and related attribute tracking method and device are capable of tracking key attribute and related attribute change and locating the code segment with the key attribute changed.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a method and device for tracking key attributes of object instances and their associated attributes. Background technique [0002] It is important and common for the information system to track application object instances. In most cases, we will record the serialization of the instance to track, but this serialization is the final result, and there is a lack of tracking of the change process of the internal attributes of the instance. The change process affects the final result. If there is a lack of tracking of the intermediate process, there will be a lack of information to judge the cause of the final result, the efficiency of locating the problem is not high, and it may also lead to errors in subsequent judgments and improvements. [0003] For instance tracking, since the instance has multiple attributes, at the business level, it will focus on the change proce...
