Class ExternalActionManager
java.lang.Object
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.
