An instance of this interface is an activity as defined by the extension
point org.eclipse.ui.activities
.
An instance of this interface can be obtained from an instance of IActivityManager
for any identifier, whether or not an activity with that identifier is
defined in the extension registry.
The handle-based nature of this API allows it to work well with runtime plugin activation and deactivation, which can cause dynamic changes to the extension registry.
This interface is not intended to be extended or implemented by clients.
