Examples of IContextActivation

org.eclipse.ui.contexts.IContextActivation

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

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