java.lang.Objectorg.eclipse.ui.actions.ActionDelegate
org.eclipse.ui.texteditor.AbstractRulerActionDelegate
This class serves as an adapter for actions contributed to the vertical ruler's
context menu. This adapter provides the contributed actions access to their editor
and the editor's vertical ruler. These actions gain only limited access to the vertical
ruler as defined by IVerticalRulerInfo
. The adapter updates the
adapter (inner) action on menu and mouse action on the vertical ruler.
Extending classes must implement the factory method
createAction(ITextEditor editor, IVerticalRulerInfo)
.

IActionDelegate
This method is called by the proxy action when the action has been triggered. Implement this method to do the actual work.
Note: If the action delegate also implements
IActionDelegate2
, then this method is not invoked but
instead the runWithEvent(IAction, Event)
method is called.

Implementers can use this opportunity to change the availability of the action or to modify other presentation properties.
When the selection changes, the action enablement state is updated based on the criteria specified in the plugin.xml file. Then the delegate is notified of the selection change regardless of whether the enablement criteria in the plugin.xml file is met.
