Callback

Description

Match

Fired when a user selects objects in 3D views and the schematic. Match determines whether an element matches the filter requirements.

Subset

Fired when a user selects subcomponents in a 3D view, or to filter the nodes displayed in an explorer view. Subset takes a collection of elements (objects or subcomponents) and determines the subset of elements that match the filter requirements.

IsApplicable

Fired by Softimage to determine whether a filter applies to the current selection (for example, a subcomponent filter does not apply to 3D objects).

Init (Filter)

Fired after the plug-in loaded (that is, after XSILoadPlugin returns). For example, Init is fired when you start Softimage or load the plug-in in the Plugin Manager.

Term

Fired when a plug-in is removed from Softimage (just before Softimage calls XSIUnloadPlugin). For example, Term is triggered when you exit Softimage or unload the plug-in.

Unload, Reload

Fired when the plug-in is cached (reloaded) and uncached (unloaded). By default, all plug-ins are cached, but users can remove a plug-in from the cache (by right-clicking a plug-in in the plug-in tree and clearing the Cached checkmark).
