Method Detail

isEmpty

public boolean isEmpty()

Description copied from interface: ISelectable

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.

Specified by:

isEmpty in interface ISelectable

Returns:

true if the selectable does not provide any descriptions.

getExportedObjects

public java.lang.Iterable<IEObjectDescription> getExportedObjects()

Specified by:

getExportedObjects in interface ISelectable

Returns:

all exported elements. May not be null.

getSelectables
