class:DefaultBoundedRangeModel [NONE]

All Implemented Interfaces:

Serializable, BoundedRangeModel
```
public class DefaultBoundedRangeModel
extends Object
implements BoundedRangeModel, Serializable
```
A generic implementation of BoundedRangeModel.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

Since:

1.2

field:changeEvent [NONE]

changeEvent
```
protected transient ChangeEvent changeEvent
```
Only one ChangeEvent is needed per model instance since the event's only (read-only) state is the source property. The source of events generated here is always "this".

field:listenerList [NONE]

listenerList
```
protected EventListenerList listenerList
```
The listeners waiting for model changes.

constructor:<init>() [NONE]

DefaultBoundedRangeModel
```
public DefaultBoundedRangeModel()
```
Initializes all of the properties with default values. Those values are:
- value = 0
- extent = 0
- minimum = 0
- maximum = 100
- adjusting = false

Specified by:

addChangeListener in interface BoundedRangeModel

Parameters:

removeChangeListener(javax.swing.event.ChangeListener), BoundedRangeModel.addChangeListener(javax.swing.event.ChangeListener)

method:removeChangeListener(javax.swing.event.ChangeListener) [NONE]

removeChangeListener
```
public void removeChangeListener(ChangeListener l)
```
Removes a ChangeListener.

method:getChangeListeners() [NONE]

getChangeListeners
```
public ChangeListener[] getChangeListeners()
```
Returns an array of all the change listeners registered on this DefaultBoundedRangeModel.

Returns:

all of this model's ChangeListeners or an empty array if no change listeners are currently registered

addChangeListener(javax.swing.event.ChangeListener), removeChangeListener(javax.swing.event.ChangeListener)

method:fireStateChanged() [NONE]

fireStateChanged
```
protected void fireStateChanged()
```
Runs each ChangeListener's stateChanged method.

method:toString() [NONE]

toString
```
public String toString()
```
Returns a string that displays all of the BoundedRangeModel properties.

Overrides:

toString in class Object

Returns:

a string representation of the object.

method:getListeners(java.lang.Class) [NONE]

getListeners
```
public <T extends EventListener> T[] getListeners(Class<T> listenerType)
```
Returns an array of all the objects currently registered as FooListeners upon this model. FooListeners are registered using the addFooListener method.
You can specify the listenerType argument with a class literal, such as FooListener.class. For example, you can query a DefaultBoundedRangeModel instance m for its change listeners with the following code:
```
ChangeListener[] cls = (ChangeListener[])(m.getListeners(ChangeListener.class));
```
If no such listeners exist, this method returns an empty array.
Type Parameters:

T - the type of EventListener class being requested

Parameters:

listenerType - the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener

Returns:

an array of all objects registered as FooListeners on this model, or an empty array if no such listeners have been added

Throws:

ClassCastException - if listenerType doesn't specify a class or interface that implements java.util.EventListener

1.3
