Constructor Detail

TLcdModelChangedEventSupport

public TLcdModelChangedEventSupport(ILcdModel aModel)

Constructs a new TLcdModelChangedEventSupport for the given model.

The model listeners of the specified model cannot be accessed directly by this object; only listeners that are explicitly registered on this object by means of the addModelListener(ILcdModelListener) method are notified of model changes.

Parameters:

aModel - the model for which the TLcdModelChangedEvent objects will be handled.

Method Detail

fireCollectedModelChanges

public void fireCollectedModelChanges()

Fires a TLcdModelChangedEvent that contains all the collected selection changes.

elementAdded

public void elementAdded(Object aObject,
                         int aEventMode)

Takes care of firing the model event after having added an Object to the model.

Parameters:

aObject - the Object that has been added to the model.

aEventMode - the mode for sending out the model event. This can be ILcdFireEventMode.FIRE_NOW, ILcdFireEventMode.LATER or ILcdFireEventMode.NO_EVENT.

elementsAdded

public void elementsAdded(Vector aObjects,
                          int aEventMode)

Takes care of firing the model event after having added several Objects to the model.

Parameters:

aObjects - the Vector of Objects that has been added to the model.

aEventMode - the mode for sending out the model event. This can be ILcdFireEventMode.FIRE_NOW, ILcdFireEventMode.LATER or ILcdFireEventMode.NO_EVENT.

elementRemoved

public void elementRemoved(Object aObject,
                           int aEventMode)

Takes care of firing the model event after having removed an Object from the model.

Parameters:

aObject - the Object that has been removed from the model.

aEventMode - the mode for sending out the model event. This can be ILcdFireEventMode.FIRE_NOW, ILcdFireEventMode.LATER or ILcdFireEventMode.NO_EVENT.

elementsRemoved

public void elementsRemoved(Vector aObjects,
                            int aEventMode)

Takes care of firing the model event after having removed several Objects from the model.

Parameters:

aObjects - the Vector of Objects that has been removed from the model.

aEventMode - the mode for sending out the model event. This can be ILcdFireEventMode.FIRE_NOW, ILcdFireEventMode.LATER or ILcdFireEventMode.NO_EVENT.

allElementsRemoved

public void allElementsRemoved(int aEventMode)

Takes care of firing the model event after having removed all Objects from the model. This call resets the mode to TLcdModelChangedEvent.ALL_OBJECTS_REMOVED and removes all model changes from the list of changes of the event that will be fired.

Parameters:

public void elementChanged(Object aObject,
                           int aEventMode)

Takes care of firing the model event after one of the Objects in the model has changed.

Parameters:

aObject - object that has changed.

aEventMode - the mode for sending out the model event. This can be ILcdFireEventMode.FIRE_NOW, ILcdFireEventMode.LATER or ILcdFireEventMode.NO_EVENT.

elementsChanged

public void elementsChanged(Vector aObjects,
                            int aEventMode)

Takes care of firing the model event after several of Objects in the model have changed.

Parameters:

aObjects - objects that have changed.

aEventMode - the mode for sending out the model event. This can be ILcdFireEventMode.FIRE_NOW, ILcdFireEventMode.LATER or ILcdFireEventMode.NO_EVENT.
