StyleContext.NamedStyle (Java Platform SE 7 )

java.lang.Object
- javax.swing.text.StyleContext.NamedStyle

All Implemented Interfaces:

Serializable, AttributeSet, MutableAttributeSet, Style

Enclosing class:

StyleContext
```
public class StyleContext.NamedStyle
extends Object
implements Style, Serializable
```
A collection of attributes, typically used to represent character and paragraph styles. This is an implementation of MutableAttributeSet that can be observed if desired. These styles will take advantage of immutability while the sets are small enough, and may be substantially more efficient than something like SimpleAttributeSet.
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^TM has been added to the java.beans package. Please see XMLEncoder.

  - listenerList
```
protected EventListenerList listenerList
```
    The change listeners for the model.
  - changeEvent
