Intermodule notification callback method and module interaction structure

Abstract

The invention discloses an intermodule notification callback method. The method includes the steps that a common information module is established, and the common information module is connected with all function modules respectively; callback functions of events or response events of all the function modules are registered in the common information module; after the common information module receives the information sent from other function modules, all the callback functions of the events which are registered in advance are called, and accordingly interaction amoung the function modules can be achieved. According to the intermodule notification callback method, module interaction work is completed by one independent common information module in a unified mode, coupling of a plurality of modules is lowered, and a software system can be maintained easily; interaction among the modules can be achieved more simply only through simple registration in the common information module; a header file of the common information module is directly cited in all the modules in which interaction is needed, the inconsistent definition condition among the modules is avoided, and the stability of the system is improved.

Description

technical field [0001] The invention relates to an information interaction technology, in particular to an inter-module notification callback method and a module interaction structure. Background technique [0002] In the software design of complex systems, multiple modules often need to cooperate and interact. The traditional method is to "create a message queue" or "register a callback function" between two modules that need to interact. [0003] like figure 1 As shown, for example, to call function Y of module B when event X occurs in module A. [0004] The method of "establishing a message queue" is: establish a message queue between module A and module B, and send a message to module B when an event X occurs in module A, and module B parses the message and calls the corresponding function. [0005] The method of "registering a callback function" is: module B first calls the registration function provided by module A to register function Y as a callback function, and t...

AI Technical Summary

Problems solved by technology

[0008] 1) Every two interactive modules need to create a message queue or register a callback function, which is more complicated to implement

[0009] 2) The coupling between modules is increased. The modification of one module will lead to the modification of multiple related modules, which is difficult to maintain

[0010] 3) Between two interactive modules, if the interface definitions on both sides are inconsistent, it may cause runtime errors and affect the stability of the system
