Examples of IHandlerActivation

org.eclipse.ui.handlers.IHandlerActivation

A token representing the activation of a handler. This token can later be used to cancel that activation. Without this token, then handler will only become inactive if the component in which the handler was activated is destroyed.

This interface is not intended to be implemented or extended by clients.
