jpicedt.graphic
Class AbstractSelectionHandler

java.lang.Object
  jpicedt.graphic.AbstractSelectionHandler

All Implemented Interfaces:

Iterable<Element>, Collection<Element>, SelectionHandler

public abstract class AbstractSelectionHandler
extends Object
implements SelectionHandler

Provides some basic implementation of the SelectionHandler interface. This implementation is based on invokations of Collection's methods. No storage mechanism is implemented in this abstract class. Concrete implementation of this mechanism should be based on mutable Java Collection's, otherwise selection operation will fail.
Finally, the content of the selection-handler is supposed to reflect the z-ordering of the Drawing it is associated with. This abstract implementation does not take care of this.
