Description

TECHNICAL FIELD

[0001] The present application relates to a system and method for data linkage between data source and view bidirectional binding. BACKGROUND

[0002] Current application development basically involves the binding problem of data source and view, and the existing framework basically solves the binding and mapping problem of single data source, that is, the so-called bidirectional binding. However, in the case of multiple data sources and mutual data linkage, the existing framework has the following problems:

[0003] 1. Easy to cause a dead loop: for example, A is linked to B, and B is linked to A, and if there is no condition to terminate the linkage, a dead loop will be caused. In the case of more linkage data, such as A is linked to B, B is linked to C,..., Z is linked to A, and H is linked to C, due to the complexity of the graph itself, it is difficult to track the problem and is not conducive to testing.

[0004] 2. Serious coupling of data sources and complex business logic: while considering data linkage, the condition to terminate the linkage also needs to be considered; each data source is seriously coupled, which is not conducive to clarifying ideas, troubleshooting, and testing.

[0005] For example Figure 1 The existing instance of bidirectional binding data linkage, the existing bidirectional binding, the binding set of view and data source is removed by data deduplication, but the loop between data sources cannot be automatically removed. In the existing way, if the mutual linkage of data sources A and B is to be removed, an additional variable needs to be recorded on the data source: data source A, B. When data source A is linked to data source B, if the source is data source B, it cannot be linked; when data source B is linked to data source A, if the source is data source A, it cannot be linked. Moreover, when data source A processes the linkage logic, the variable of data source B needs to be recorded, that is, the binding set A needs to be coupled with the logic of the binding set B. If there are multiple data linkages, the coupling will be very serious and chaotic. The current binding architecture of data source and view is difficult to meet the complex linkage demand. SUMMARY

[0006] The purpose of the present application is to provide a system and method for data linkage between data source and view bidirectional binding to solve the problems raised in the background art.

[0007] To achieve the above purpose, the present application provides the following technical scheme:

[0027] The downstream data source is linked to the view, and the linkage is terminated by deduplicating the data.
