public interface Labeled

Interface for Objects which have a Label. For instance, they may be hand-classified with one or more tags. Note that it is for things that possess a label via composition, rather than for things that implement the Label interface. An implementor might choose to be read-only and throw an UnsupportedOperationException on the setLabel(s)() commands, but should minimally implement both commands to return Label(s).

Method Summary

Label	label() Returns the Object's label.
Collection	labels() Gives back all labels for this thing.
void	setLabel(Label label) Sets the label associated with this object.
void	setLabels(Collection labels) Sets the labels associated with this object.
