Eclipse Platform
Release 3.5

org.eclipse.jface.action
Class ExternalActionManager

java.lang.Object
  extended by 
org.eclipse.jface.action.ExternalActionManager

public final class ExternalActionManager
extends Object

A manager for a callback facility which is capable of querying external interfaces for additional information about actions and action contribution items. This information typically includes things like accelerators and textual representations.

It is only necessary to use this mechanism if you will be using a mix of actions and commands, and wish the interactions to work properly.

For example, in the Eclipse workbench, this mechanism is used to allow the command architecture to override certain values in action contribution items.

This class is not intended to be called or extended by any external clients.
