Class AbstractCommand

java.lang.Object
  org.springframework.binding.value.support.AbstractPropertyChangePublisher
      org.springframework.richclient.command.AbstractCommand

All Implemented Interfaces:

BeanNameAware, InitializingBean, PropertyChangePublisher, ActionCommandExecutor, GuardedActionCommandExecutor, Authorizable, Guarded, SecurityControllable

Direct Known Subclasses:

ActionCommand, CommandGroup

public abstract class AbstractCommand
extends AbstractPropertyChangePublisher
implements InitializingBean, BeanNameAware, GuardedActionCommandExecutor, SecurityControllable

Base class for commands. Extend this class by implementing the ActionCommandExecutor.execute() method.

Most (if not all) commands result in a UI component. Several methods are provided here to deliver abstractButtons or menuItems. Configuring this visual aspect of the command is done by a number of CommandFaceDescriptors. One of these will be registered as the default while others can be used to create a different look by providing a faceDescriptorId.
