Creates a Listener.MultiplexListener.

Method Detail

beforeSet

public void beforeSet(Observable obj,
                      String property,
                      Object value)

Description copied from interface: Listener

Informs this Listener that the value of the given property is to be modified.

Specified by:

beforeSet in interface Listener

Parameters:

obj - The Observable object.

property - The name of the property to be modified.

value - The new value that is being set to the given property.

beforeAdd

public void beforeAdd(Observable obj,
                      String property,
                      int index,
                      Object element)

Description copied from interface: Listener

Informs this Listener that an element will be added to the repeated property with the given name.

Specified by:

beforeAdd in interface Listener

Parameters:

obj - The Observable object.

property - The name of the property to be modified.

index - The index where the new element will be added if the property is ordered, -1 otherwise.

element - The new element that is being added to the given property.

afterRemove

public void afterRemove(Observable obj,
                        String property,
                        int index,
                        Object element)

Description copied from interface: Listener

Informs this Listener that an element was removed from a repeated property with the given name.

Specified by:

afterRemove in interface Listener

Parameters:

obj - The Observable object.

property - The name of the property to be modified.

index - The index where the element was removed if the property is ordered, -1 otherwise.

element - The element that was removed from the given property.

afterChanged

public void afterChanged(Observable obj,
                         String property)

Description copied from interface: Listener

Informs this Listener that the property of an element was changed.

This method is also called after all other methods to indicate that a property has been changed. It is not called more than once for bulk operations (e.g. adding several objects to a list)

Specified by:

afterChanged in interface Listener

Parameters:

obj - The Observable object.

property - The name of the property to be modified.

register

public Listener register(Listener l)

unregister

public Listener unregister(Listener removed)
