All Implemented Interfaces:
Serializable, SpinnerModel
Direct Known Subclasses:
SpinnerDateModel, SpinnerListModel, SpinnerNumberModel

public abstract class AbstractSpinnerModel

1.4

Field Detail

listenerList

protected EventListenerList listenerList
The list of ChangeListeners for this model. Subclasses may store their own listeners here.

Constructor Detail

AbstractSpinnerModel

public AbstractSpinnerModel()
Method Detail

addChangeListener

public void addChangeListener(ChangeListener l)
Adds a ChangeListener to the model's listener list. The ChangeListeners must be notified when the models value changes.

Specified by:
addChangeListener in interface SpinnerModel
Parameters:
l - the ChangeListener to add
See Also:
removeChangeListener(javax.swing.event.ChangeListener), SpinnerModel.addChangeListener(javax.swing.event.ChangeListener)

removeChangeListener

public void removeChangeListener(ChangeListener l)
Removes a ChangeListener from the model's listener list.

Specified by:
removeChangeListener in interface SpinnerModel
Parameters:
l - the ChangeListener to remove
See Also:
addChangeListener(javax.swing.event.ChangeListener), SpinnerModel.removeChangeListener(javax.swing.event.ChangeListener)

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

fireStateChanged

protected void fireStateChanged()
Run each ChangeListeners stateChanged() method.

See Also:
SpinnerModel.setValue(java.lang.Object), EventListenerList

getListeners

public <T extends EventListener> T[] getListeners(Class<T> 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
