Class AbstractSpinnerModel

• java.lang.Object
• • javax.swing.AbstractSpinnerModel

All Implemented Interfaces:

Serializable, SpinnerModel

Direct Known Subclasses:

SpinnerDateModel, SpinnerListModel, SpinnerNumberModel

public abstract class AbstractSpinnerModel
extends Object
implements SpinnerModel, Serializable

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.

Since:

1.4

See Also:

JSpinner, SpinnerModel, SpinnerListModel, SpinnerNumberModel, SpinnerDateModel

Fields

listenerList

protected EventListenerList listenerList

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

Constructors

AbstractSpinnerModel

public AbstractSpinnerModel()

Methods

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
