Since:
1.4

removeChangeListener(ChangeListener), SpinnerModel.addChangeListener(ChangeListener)

extends EventListener> T[] getListeners

public extends EventListener> T[] getListeners(Class listenerType)
Return an array of all the listeners of the given type that were added to this model. For example to find all of the ChangeListeners added to this model: 
 myAbstractSpinnerModel.getListeners(ChangeListener.class);
Parameters:
listenerType - the type of listeners to return, e.g. ChangeListener.class
Returns:
all of the objects receiving listenerType notifications from this model

fireStateChanged

protected void fireStateChanged()
Run each ChangeListeners stateChanged() method.
See Also:
AbstractSpinnerModel, EventListenerList

getChangeListeners

public ChangeListener[] getChangeListeners()
Returns an array of all the ChangeListeners added to this AbstractSpinnerModel with addChangeListener().
Returns:
all of the ChangeListeners added or an empty array if no listeners have been added
Since:
1.4

removeChangeListener

public void removeChangeListener(ChangeListener l)
