- 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.

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 interfaceSpinnerModel
- 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 interfaceSpinnerModel
- 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 ChangeListener
s added to this AbstractSpinnerModel with addChangeListener().
- Returns:
- all of the
ChangeListener
s added or an empty array if no listeners have been added - Since:
- 1.4
fireStateChanged
protected void fireStateChanged()
Run each ChangeListeners stateChanged() method.
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);
- Type Parameters:
-
T
- the type of requested listeners - Parameters:
-
listenerType
- the type of listeners to return, e.g. ChangeListener.class - Returns:
- all of the objects receiving listenerType notifications from this model
