  it.amattioli.applicate.commands.AbstractCommand

All Implemented Interfaces:

Command, ValuesLister, it.amattioli.dominate.util.PropertyChangeEmitter

Direct Known Subclasses:

NullCommand, TreeEditorCommand, UndoAvailableCommand, UndoCommand

public abstract class AbstractCommand
extends Object
implements Command, it.amattioli.dominate.util.PropertyChangeEmitter, ValuesLister

This class is a base implementation of the Command interface. It implements the two addCommandListener methods and fires a CommandEvent when doCommand() and cancelCommand() are called with CommandResult.SUCCESSFUL and CommandResult.CANCELLED respectively. This class implements PropertyChangeEmitter too, so extenders can fire PropertyChangeEvent when a command property changes.
