Method and device for realizing function mandate

Abstract

The invention provides a method for realizing function mandate. In the method, the mandate function of a function is used for mandating a function to be mandated to a progress in a component-based software system, a destructor function is used to call and execute the mandated function when the progress to which the function mandated quits and enters into a ready ending state, thereby improving mandating efficiency of the function and avoiding the mandate error of the function and the damage of a program structure. The invention further provides a data processing device for realizing the function mandating.

Description

technical field [0001] The present invention relates to a method and device for realizing function management and control, in particular to a method and device for realizing function hosting. Background technique [0002] With the continuous development of computer software technology, component software technology has become more and more popular, and various component technologies and corresponding embedded operating systems supporting these component technologies have emerged as the times require. [0003] At present, when people use the componentized software system platform for programming, for example, when programming on the Elastos platform developed by Shanghai Ketai Century Technology Co., Ltd., they may want to be notified of the process exit, so that when the process exits and enters the ready-to-end state Do some resource cleaning work, or set some flags, send message notifications, etc. when the process exits and enters the ready-to-end state. However, there ar...

Problems solved by technology

[0004] Question 1: Although the exit of the main thread means the exit of the process, there are two constraints

First, when the main thread exits, it only returns to the message loop of the main thread, which does not mean that the current process or the main thread has exited. After entering the message loop, it leaves the user's code, and the user cannot know exactly when the message loop ends. 1. When the main thread exits; Second, during the running process, a submodule or loaded third-party DLL library cannot modify the main thread of the process or other codes beyond its scope, so it cannot be obtained when the main thread exits When to call your own code

[0005] Question 2: Although the user can use the "thread managed function" method to host the function on the main thread, host a function on the main thread, and when the main thread finishes exiting, it will call this function to be notified indirectly, but this managed Function calls must be executed on the main thread, which is cumbersome for users. If there are many functions to be hosted, different functions may be attached to different threads, and different functions may be run by different codes or even different third parties. The code to create, etc. These circumstances make this method more complicated to operate, more error-prone, and even destroy the program structure
