org.eclipse.ui.internal.commands.CommandStateProxy

CommandStateProxy
final public class CommandStateProxy extends PersistentState (Code)

A proxy for handler state that has been defined in XML. This delays the class loading until the state is really asked for information. Asking a proxy for anything (except disposing, and adding and removing listeners) will cause the proxy to instantiate the proxied handler.

Loading the proxied state will automatically cause it to load its value from the preference store. Disposing of the state will cause it to persist its value.

This class is not intended for use outside of the org.eclipse.ui.workbench plug-in.


since:
   3.2
