OpenJDK 27 · javax.swing.AbstractSpinnerModel · APIdia, the JavaDoc alternative

This class provides the ChangeListener part of the SpinnerModel interface that should be suitable for most concrete SpinnerModel implementations. Subclasses must provide an implementation of the setValue, getValue, getNextValue and getPreviousValue methods.

Field Summary

Modifier and Type	Field and Description
private transient ChangeEvent	changeEvent Only one ChangeEvent is needed per model instance since the event's only (read-only) state is the source property.
protected EventListenerList	listenerList The list of ChangeListeners for this model.

Constructor Summary

Access	Constructor and Description
protected	AbstractSpinnerModel() Constructor for subclasses to call.

Method Summary

Modifier and Type	Method and Description
public void	addChangeListener(ChangeListener the ChangeListener to add l) Implements javax.swing.SpinnerModel.addChangeListener. Adds a ChangeListener to the model's listener list.
protected void	fireStateChanged() Run each ChangeListeners stateChanged() method.
public ChangeListener[]	Returns: all of the `ChangeListener`s added or an empty array if no listeners have been added getChangeListeners() Returns an array of all the `ChangeListener`s added to this AbstractSpinnerModel with addChangeListener().
public < the type of requested listeners T extends EventListener> T[]	Returns: all of the objects receiving listenerType notifications from this model getListeners(Class<T> the type of listeners to return, e.g. ChangeListener.class listenerType) Return an array of all the listeners of the given type that were added to this model.
public void	removeChangeListener(ChangeListener the ChangeListener to remove l) Implements javax.swing.SpinnerModel.removeChangeListener. Removes a ChangeListener from the model's listener list.

private transient ChangeEvent changeEvent Only one ChangeEvent is needed per model instance since the event's only (read-only) state is the source property. The source of events generated here is always "this".

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

Method Detail

addChangeListener back to summary

addChangeListener	back to summary
public void addChangeListener(ChangeListener l) Implements javax.swing.SpinnerModel.addChangeListener. Adds a ChangeListener to the model's listener list. The ChangeListeners must be notified when the models value changes. Parameters l:ChangeListener the ChangeListener to add See Also `removeChangeListener`, `SpinnerModel#addChangeListener`

public void addChangeListener(ChangeListener l)

Implements javax.swing.SpinnerModel.addChangeListener.

Adds a ChangeListener to the model's listener list. The ChangeListeners must be notified when the models value changes.

Parameters

l:ChangeListener: the ChangeListener to add

fireStateChanged back to summary

fireStateChanged	back to summary
protected void fireStateChanged() Run each ChangeListeners stateChanged() method. See Also `setValue`, `EventListenerList`

protected void fireStateChanged()

Run each ChangeListeners stateChanged() method.

See Also: setValue, EventListenerList

getChangeListeners back to summary

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

public ChangeListener[] getChangeListeners()

Returns an array of all the ChangeListeners added to this AbstractSpinnerModel with addChangeListener().

Returns:ChangeListener[]: all of the ChangeListeners added or an empty array if no listeners have been added
Since: 1.4

getListeners	back to summary
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 <T> the type of requested listeners listenerType:Class<T> the type of listeners to return, e.g. ChangeListener.class Returns:T[] all of the objects receiving listenerType notifications from this model

getListeners

back to summary

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

<T>: the type of requested listeners
listenerType:Class<T>: the type of listeners to return, e.g. ChangeListener.class

Returns:T[]

all of the objects receiving listenerType notifications from this model

removeChangeListener back to summary

removeChangeListener	back to summary
public void removeChangeListener(ChangeListener l) Implements javax.swing.SpinnerModel.removeChangeListener. Removes a ChangeListener from the model's listener list. Parameters l:ChangeListener the ChangeListener to remove See Also `addChangeListener`, `SpinnerModel#removeChangeListener`

public void removeChangeListener(ChangeListener l)

Implements javax.swing.SpinnerModel.removeChangeListener.

Removes a ChangeListener from the model's listener list.

Parameters

l:ChangeListener: the ChangeListener to remove
