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

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

    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

    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
