javax.swing.AbstractSpinnerModel
- All Implemented Interfaces:
Serializable
,SpinnerModel
- Direct Known Subclasses:
SpinnerDateModel
,SpinnerListModel
,SpinnerNumberModel
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

addChangeListener
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
Removes a ChangeListener from the model's listener list.- Specified by:
removeChangeListener
in interfaceSpinnerModel
- Parameters:
l
- the ChangeListener to remove- See Also:
-
getChangeListeners
Returns an array of all theChangeListener
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.- See Also:
-
getListeners
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
