Object Hierarchy | Related C++ Class: PluginRegistrar







The PluginRegistrar object is used by plug-in modules for registering plug-in items in Softimage along with other general information. The object is created by Softimage and contains information such as the directory where the plug-in is being loaded/unloaded and the filename of the plug-in.

When Softimage starts up, a PluginRegistrar object is created for each plug-in to load and passed to the XSILoadPlugin function entry point exposed by the plug-in. The information gathered by Softimage is used for creating the plug-in items when required by the user.

When a plug-in is unloaded, a PluginRegistrar object is created for this particular plug-in and passed to the XSIUnloadPlugin function entry point exposed by the plug-in (see Callbacks for Self-Installing Plug-ins). The information registered by the plug-in can be accessed through the Plugin object.
