public abstract class AbstractManager<E extends NamedBean>
extends VetoableChangeSupport
implements Manager<E>, PropertyChangeListener, VetoableChangeListener

- deleteBean
  
  @OverridingMethodsMustInvokeSuper public void deleteBean(@Nonnull E bean, @Nonnull String property) throws PropertyVetoException
  
  Method for a UI to delete a bean.
  The UI should first request a "CanDelete", this will return a list of locations (and descriptions) where the bean is in use via throwing a VetoException, then if that comes back clear, or the user agrees with the actions, then a "DoDelete" can be called which inform the listeners to delete the bean, then it will be deregistered and disposed of.
  If a property name of "DoNotDelete" is thrown back in the VetoException then the delete process should be aborted.
  
  Specified by:
  
  deleteBean in interface Manager<E extends NamedBean>
  
  Parameters:
  
  bean - The NamedBean to be deleted
  
  property - The programmatic name of the request. "CanDelete" will enquire with all listeners if the item can be deleted. "DoDelete" tells the listener to delete the item
  
  Throws:
  
  PropertyVetoException - If the recipients wishes the delete to be aborted (see above)
- register
  
  @OverridingMethodsMustInvokeSuper public void register(@Nonnull E s)
  
  Remember a NamedBean Object created outside the manager.

  register in interface Manager<E extends NamedBean>
  
  Parameters:
  
  s - the bean
- registerUserName
  
  protected void registerUserName(E s)
  
  Invoked by register(NamedBean) to register the user name of the bean.
  
  Parameters:
  
  s - the bean to register
- handleUserNameUniqueness
  
  protected void handleUserNameUniqueness(E s)
  
  Invoked by registerUserName(NamedBean) to ensure uniqueness of the NamedBean during registration.
  
  Parameters:
  
  s - the bean to register
- deregister
  
  @OverridingMethodsMustInvokeSuper public void deregister(@Nonnull E s)
  
  Forget a NamedBean Object created outside the manager.
  The non-system-specific RouteManager uses this method.
  
  Specified by:
  
  deregister in interface Manager<E extends NamedBean>
  
  Parameters:
  
  s - the bean
- getKnownBeanProperties
  
  @Nonnull public List<NamedBeanPropertyDescriptor<?>> getKnownBeanProperties()

  Returns:
  
  empty list

  Parameters:
  
  e - the event
- getObjectCount
  
  @CheckReturnValue public int getObjectCount()

  Specified by:
  
  getObjectCount in interface Manager<E extends NamedBean>
  
  Returns:
  
  the number of managed objects

  Deprecated.
  
  Provide an unmodifiable List of system names.

  Specified by:
  
  getSystemNameList in interface Manager<E extends NamedBean>
  
  Returns:
  
  Unmodifiable access to a list of system names
- getNamedBeanList

- fireVetoableChange
  
  @OverridingMethodsMustInvokeSuper public void fireVetoableChange(String p, Object old, Object n) throws PropertyVetoException
  
  Inform all registered listeners of a vetoable change. If the propertyName is "CanDelete" ALL listeners with an interest in the bean will throw an exception, which is recorded returned back to the invoking method, so that it can be presented back to the user. However if a listener decides that the bean can not be deleted then it should throw an exception with a property name of "DoNotDelete", this is thrown back up to the user and the delete process should be aborted.
  
  Specified by:
  
  fireVetoableChange in interface VetoableChangeFirer
  
  Overrides:
  
  fireVetoableChange in class VetoableChangeSupport
  
  Parameters:
  
  p - The programmatic name of the property that is to be changed. "CanDelete" will inquire with all listeners if the item can be deleted. "DoDelete" tells the listener to delete the item.
  
  old - The old value of the property.

  Throws:
  
  PropertyVetoException
- validSystemNameFormat

  Test if parameter is a properly formatted system name. Implementations of this method must not throw an exception, log an error, or otherwise disrupt the user.
  
  Specified by:
  
  validSystemNameFormat in interface Manager<E extends NamedBean>
  
  Parameters:
  
  systemName - the system name
  
  Returns:
  
  Manager.NameValidity.INVALID if system name does not start with Manager.getSystemNamePrefix(); Manager.NameValidity.VALID_AS_PREFIX_ONLY if system name equals Manager.getSystemNamePrefix(); otherwise Manager.NameValidity.VALID to allow Managers that do not perform more specific validation to be considered valid.
- getSystemPrefix
  
  @Nonnull public final String getSystemPrefix()
  
  Provide access to the system prefix string. This was previously called the "System letter" The implementation in AbstractManager should be final, but is not for four managers that have arbitrary prefixes.
  
  Specified by:
  
  getSystemPrefix in interface Manager<E extends NamedBean>
  
  Returns:
  
  the system prefix
- setPropertyChangesSilenced
  
  @OverridingMethodsMustInvokeSuper public void setPropertyChangesSilenced(@Nonnull String propertyName, boolean silenced)
  
  Suppress sending PropertyChangeEvents for the named property.
  Stopping the suppression of sending change events may send a PropertyChangeEvent if the property changed while silenced, but otherwise should not fire a PropertyChangeEvent.
  
  Specified by:
  
  setPropertyChangesSilenced in interface SilenceablePropertyChangeProvider
  
  Parameters:
  
  propertyName - the name of the property to mute
  
  silenced - true if events are to be suppressed; false otherwise
- addDataListener
  
  @Deprecated public void addDataListener(Manager.ManagerDataListener<E> e)
  
  Deprecated.
  
  Register a Manager.ManagerDataListener to hear about adding or removing items from the list of NamedBeans.
  
  Specified by:
  
  addDataListener in interface Manager<E extends NamedBean>
  
  Parameters:
  
  e - the data listener to add
- removeDataListener
  
  @Deprecated public void removeDataListener(Manager.ManagerDataListener<E> e)
  
  Deprecated.
  
  Unregister a previously-added Manager.ManagerDataListener.
  
  Specified by:
  
  removeDataListener in interface Manager<E extends NamedBean>
  
  Parameters:
  
  e - the data listener to remove
  
  See Also:
  
  Manager.addDataListener(ManagerDataListener)
- setDataListenerMute
  
  @Deprecated public void setDataListenerMute(boolean m)
  
  Deprecated.
  
  Temporarily suppress DataListener notifications.
  This avoids O(N^2) behavior when doing bulk updates, i.e. when loading lots of Beans. Note that this is (1) optional, in the sense that the manager is not required to mute and (2) if present, its' temporary, in the sense that the manager must do a cumulative notification when done.
  
  Specified by:
  
  setDataListenerMute in interface Manager<E extends NamedBean>
  
  Parameters:
  
  m - true if notifications should be suppressed; false otherwise
