/**
* <p>
* An extension to a standard launch shortcut ({@link ILaunchShortcut}) allowing
* launch shortcuts to specify how selections and editors should be launched.
* </p>
* <p>
* To launch a selection (or active editor), the debug platform derives a resource associated
* with the selection (or active editor), and then resolves the most recently launched configuration
* associated with that resource. This interface allows a launch shortcut to override the
* framework's resource and launch configuration resolution for selections (and active editors).
* </p>
* <p>
* NOTE: the methods in this interface can be called in a <b>non-UI</b> thread.
* </p>
* <p>
* Clients contributing a launch shortcut are intended to implement this interface.
* </p>
