Class ActionSetManager

java.lang.Object

org.eclipse.ui.internal.ActionSetManager

public class ActionSetManager
extends Object

Maintains a reference counted set of action sets, with a visibility mask. This is used to determine the visibility of actions in a workbench page. In a workbench page, there may be may be many conditions that can cause an action set to become visible (such as the active part, the active editor, the default visibility of the action, the properties of the perspective, etc.) The user can also explicitly mask off particular action sets in each perspective.

The reference count indicates how many conditions have requested that the actions be active and the mask indicates whether or not the set was disabled by the user.
