Constructor Detail

ObservableSortedSetChangeSupport

protected ObservableSortedSetChangeSupport()

Create a new support class meant to be subclassed.

ObservableSortedSetChangeSupport

public ObservableSortedSetChangeSupport(ObservableSortedSet<E> source)

Create a new support class that fires sorted set change and vetoable sorted set change events with the specified source as the source of the events.

Parameters:

source - the event source

Method Detail

setSource

protected void setSource(ObservableSortedSet<E> source)

Set the source of sorted set change and vetoable sorted set change events to source. Subclasses should call this method before any of the fireX methods.

Parameters:

source - the event source

getEventListenerList

protected final EventListenerList getEventListenerList()

Return the EventListenerList backing this observable sorted set support class.

Returns:

the EventListenerList backing this observable sorted set support class.

addSortedSetChangeListener

public final void addSortedSetChangeListener(SortedSetChangeListener<E> l)

Add the specified sorted set change listener.

Parameters:

l - sorted set change listener to add

removeSortedSetChangeListener

public final void removeSortedSetChangeListener(SortedSetChangeListener<E> l)

Remove the specified sorted set change listener.

Parameters:

l - sorted set change listener to remove

addVetoableSortedSetChangeListener

public final void addVetoableSortedSetChangeListener(VetoableSortedSetChangeListener<E> l)

Add the specified vetoable sorted set change listener.

Parameters:

l - vetoable sorted set change listener to add

removeVetoableSortedSetChangeListener

public final void removeVetoableSortedSetChangeListener(VetoableSortedSetChangeListener<E> l)

Remove the specified vetoable sorted set change listener.

Parameters:

l - vetoable sorted set change listener to remove

getSortedSetChangeListeners

public final SortedSetChangeListener<E>[] getSortedSetChangeListeners()

Return an array of all SortedSetChangeListeners, or an empty array if none are registered.

Returns:

an array of all SortedSetChangeListeners, or an empty array if none are registered

getSortedSetChangeListenerCount

public final int getSortedSetChangeListenerCount()

Return the number of SortedSetChangeListeners registered to this observable sorted set support class.

Returns:

the number of SortedSetChangeListeners registered to this observable sorted set support class

getVetoableSortedSetChangeListeners

public final VetoableSortedSetChangeListener<E>[] getVetoableSortedSetChangeListeners()

Return an array of all VetoableSortedSetChangeListeners, or an empty array if none are registered.

Returns:

an array of all VetoableSortedSetChangeListeners, or an empty array if none are registered

getVetoableSortedSetChangeListenerCount

public final int getVetoableSortedSetChangeListenerCount()

Return the number of VetoableSortedSetChangeListeners registered to this observable sorted set support class.
