Method and device for interaction between host program and plug-in and interaction between plug-ins

Abstract

The invention discloses a method for the interaction between a host program and a plug-in and the interaction between plug-ins, which sets a common protocol for the interaction between the host program and the plug-in. The method also comprises the following steps: a host interface entity is created on the basis of the common protocol after the host program is started; in the process that the host program loads the plug-in, the plug-in generates a plug-in interface entity based on the set common protocol, the host program saves the generated plug-in interface entity, and the plug-in saves the host interface entity created by the host program; and the host program and the plug-in complete the interaction operation by saving the interface entity of the counterpart. The invention also discloses a device for the interaction between a host program and a plug-in and the interaction between plug-ins, which can realize the two-way interaction between the host program and the plug-in and the two-way interaction between the plug-ins.

Description

technical field [0001] The invention relates to a plug-in interaction technology in an application program, in particular to a method and a device for interacting between a host program and a plug-in and between plug-ins. Background technique [0002] Traditional applications are composed of main executable programs, configuration files, data files, pictures and other information, and some specific functions are loaded in the application as required, such as dynamic link libraries for codec functions, data compression functions, etc. With the development of programming technology, modules with specific functions in current applications are generally implemented through plug-ins, such as sound decoding plug-ins in Winamp and so on. However, the existing plug-in technology has the following deficiencies: [0003] 1) As the callback function is used to complete the interaction between the host program and the plug-in, the interaction between the host program and the plug-in is...

AI Technical Summary

Problems solved by technology

[0004] 2) The host program and the plug-in cannot interact through manual selection, that is, the interaction between the host program and the plug-in is carried out within the application program, and the user cannot select the required plug-in function on the visual interface;

[0005] 3) The plug-in can only be called by the host program, and the plug-ins cannot call each other
