Problems solved by technology

[0006] At present, in the process of using and managing plug-ins, for different plug-in implementation methods: whether it is a static shared library or a dynamic shared library, if it is a dynamic shared library, and under which operating system is it implemented, only different methods can be used. and management mechanism, which damages the cross-platform scalability of the program and brings difficulties to the transplantation of the program

Embodiment Construction

[0032] Such as figure 1 As shown, the present invention provides a plug-in management method, which includes the following steps:

[0033] A. Abstract the operation interface of the plug-in and encapsulate it into an upper-layer calling interface;

[0034] B. When the called plug-in is loaded, the obtained plug-in handle is stored and marked in the memory, and the corresponding relationship between the plug-in handle and the plug-in management information is established; the plug-in management information here includes at least: plug-in name, plug-in handle, plug-in called count, and the resident memory attribute bit.

[0035] C. Perform loading, unloading, or search operations on the called plug-in through the upper-layer call interface and the corresponding relationship between the plug-in handle in the memory and the plug-in management information.

[0036] In order to store the corresponding relationship between the above-mentioned plug-in handle and plug-in management i...

Abstract

The invention discloses a method for managing a plug-in and a system thereof. The method comprises the following steps: A, abstracting the operation interface of the plug-in and encapsulating the interface into an upper-level invocation interface; B, storing obtained plug-in handle and marking in a memory when loading the plug-in needs to be invoked, and establishing the corresponding relationship between the plug-in handle and the plug-in management information; and C, conducting loading, unloading or searching operation to the plug-in to be invoked according to the upper-level invocation interface and the corresponding relationship between the plug-in handle and the plug-in management information in the memory. The invention realizes unified storage, operation and management to the plug-in, and particularly aims to solve the difference between static loading and dynamic loading of a shared library, thereby enlarging use range of programs to plug-ins, improving the cross-platform expansibility of programs, and facilitating the transplantation of programs.

Description

technical field [0001] The invention relates to plug-in management technology, in particular to a technical field of how to realize plug-in management in a cross-platform environment. Background technique [0002] Plugin (plugin), refers to the shared library. When the shared library is called, no matter how many running programs are called at the same time, there is only one copy of the shared library in the memory, and the code and read-only data segments of the shared library are reused during the running of the program to save system memory purpose of the resource. [0003] The dynamic loading of shared libraries represents the development direction of shared libraries, and plug-ins in a narrow sense usually refer to such shared libraries. Dynamic loading separates the linking and loading of the plug-in from the linking and loading process of the calling program, so that the linking and loading of the plug-in is delayed until the program starts, or even after the progr...
