org.eclipse.ui.actions.BaseSelectionListenerAction

The abstract superclass for actions that listen to selection change events. This implementation tracks the current selection (see getStructuredSelection) and provides a convenient place to monitor selection changes that could affect the availability of the action.

Subclasses must implement the following IAction method:

run - to do the action's work

Subclasses may extend the updateSelection method to update the action determine its availability based on the current selection.

The object instantiating the subclass is responsible for registering the instance with a selection provider. Alternatively, the object can notify the subclass instance directly of a selection change using the methods:

selectionChanged(IStructuredSelection) - passing the selection
selectionChanged(ISelectionChangedEvent) - passing the selection change event
