AbstractSpinnerModel (Java Platform SE 8 ) (original) (raw)

• 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 thesetValue, getValue, getNextValue andgetPreviousValue methods.
Since:
1.4
See Also:
JSpinner, SpinnerModel, SpinnerListModel, SpinnerNumberModel, SpinnerDateModel

• • Field Detail

     * #### listenerList  
     protected [EventListenerList](../../javax/swing/event/EventListenerList.html "class in javax.swing.event") listenerList  
     The list of ChangeListeners for this model. Subclasses may store their own listeners here.  

  • Constructor Detail

  • Method Detail

    * #### addChangeListener  
    public void addChangeListener([ChangeListener](../../javax/swing/event/ChangeListener.html "interface in javax.swing.event") l)  
    Adds a ChangeListener to the model's listener list. The ChangeListeners must be notified when the models value changes.  
    Specified by:  
    `[addChangeListener](../../javax/swing/SpinnerModel.html#addChangeListener-javax.swing.event.ChangeListener-)` in interface `[SpinnerModel](../../javax/swing/SpinnerModel.html "interface in javax.swing")`  
    Parameters:  
    `l` \- the ChangeListener to add  
    See Also:  
    [removeChangeListener(javax.swing.event.ChangeListener)](../../javax/swing/AbstractSpinnerModel.html#removeChangeListener-javax.swing.event.ChangeListener-), [SpinnerModel.addChangeListener(javax.swing.event.ChangeListener)](../../javax/swing/SpinnerModel.html#addChangeListener-javax.swing.event.ChangeListener-)  
    * #### removeChangeListener  
    public void removeChangeListener([ChangeListener](../../javax/swing/event/ChangeListener.html "interface in javax.swing.event") l)  
    Removes a ChangeListener from the model's listener list.  
    Specified by:  
    `[removeChangeListener](../../javax/swing/SpinnerModel.html#removeChangeListener-javax.swing.event.ChangeListener-)` in interface `[SpinnerModel](../../javax/swing/SpinnerModel.html "interface in javax.swing")`  
    Parameters:  
    `l` \- the ChangeListener to remove  
    See Also:  
    [addChangeListener(javax.swing.event.ChangeListener)](../../javax/swing/AbstractSpinnerModel.html#addChangeListener-javax.swing.event.ChangeListener-), [SpinnerModel.removeChangeListener(javax.swing.event.ChangeListener)](../../javax/swing/SpinnerModel.html#removeChangeListener-javax.swing.event.ChangeListener-)  
    * #### getChangeListeners  
    public [ChangeListener](../../javax/swing/event/ChangeListener.html "interface in javax.swing.event")[] 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.  
    See Also:  
    [SpinnerModel.setValue(java.lang.Object)](../../javax/swing/SpinnerModel.html#setValue-java.lang.Object-), [EventListenerList](../../javax/swing/event/EventListenerList.html "class in javax.swing.event")  
    * #### getListeners  
    public <T extends [EventListener](../../java/util/EventListener.html "interface in java.util")> T[] getListeners([Class](../../java/lang/Class.html "class in java.lang")<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
