Method for implementing event call-back based on component interface in computer software system

Abstract

The invention relates to a method of realizing event callback based on a component interface in a computer software system, which comprises that: a definition information of a callback interface and an event method in the callback interface of target component class is generated at service end, a callback function definition information corresponding to the event method in the callback interface of the component class is generated at client end, an object example of the target component class is established at service end, a correlation registration processing operation is carried through between the callback event of the object example of the target class at service end and the callback function at client end, the backcall event is excitated and the callback function registered in correlation with the callback event is called according to the operation of the object example of the target component class. By adopting the method of realizing event callback based on the component interface in the computer software system, the invention has simple and convenient realization, flexible operation, powerful function, stable and reliable performance and relatively wide application scope, as well as establishes a steady basis to the further development of the computer component software system.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to the technical field of computer componentized software systems, and specifically refers to a method for implementing event callback based on component interfaces in a computer software system. Background technique [0002] In the development of modern computer software technology, the callback function is a very useful programming mechanism, which has been in the field of programming for many years. Program developers can use this mechanism to compile various applications. Powerful, yet very flexible, and easy to implement. [0003] However, in the prior art, the usual Windows message callback model is completely process-oriented, and the sender decides who to send to, while the receiver can only silently receive and process all messages or even junk messages; at the same time, the sender Sending a message and processing the message at the receiving end require the use...
