Interface IContext
-
- All Superinterfaces:
Comparable
@Deprecated public interface IContext extends Comparable
Deprecated.Please use the "org.eclipse.core.commands" plug-in instead.An instance of this interface is an context as defined by the extension pointorg.eclipse.ui.contexts
.An instance of this interface can be obtained from an instance of
IContextManager
for any identifier, whether or not an context 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. If a context is defined, that means that its corresponding plug-in is active. If the plug-in is then deactivated, the context will still exist but it will be undefined. An attempts to use an undefined context will result in a
NotDefinedException
being thrown.This interface is not intended to be extended or implemented by clients.
- Since:
- 3.0
