public interface ILaunchable
The debug platform uses the ILaunchable
interface as a tag for
objects that can be launched via the context menu 'Run As / Debug As' actions
and run/debug tool bar buttons. The platform checks if an ILaunchable
adapter is available from the selection/active editor to determine if it
should be considered for launching. However, the platform never actually
retrieves the adapter or calls any methods on it (the interface is, in fact, empty).
The debug platform performs the following test:
Platform.getAdapterManager().hasAdapter(X, ILaunchable.class.getName());
Thus objects that can be launched need to register ILaunchable
adapters, but
don't have to provide implementations. There is also no harm in implementing the interface
or providing the adapter. For example, JDT contributes an adapter as follows. Although
no adapter is actually provided the platform will answer true
to
hasAdapter(...)
.
Clients may contribute an adapter of this type for launchable objects
via the org.eclipse.core.runtime.adapters
extension
point. A factory and implementation of this interface are not actually
required.
Clients that need to check for presence of launchable adapter using standard expression mechanism, should use a property tester as follows:
