public interface ISelectable
An ISelectable
is something that can be queried for exported object.
Thereby it serves as a common abstract super concept for IContainer
and
IResourceDescription
.
Furthermore there is an implementation of the IScope
interface that is based on ISelectable
and vice versa.
All implementations of ISelectable
can deal with ignore case and case sensitive queries.

isEmpty
boolean isEmpty()
- Clients may want to check the selectable to skip its processing in case it is empty.
Implementations should be fast and not require expensive precalculation. Selectable may
return
false
if it is too expensive to compute the actual result.
- Returns:
true
if the selectable does not provide any descriptions.
