## javax.swing.text
Class StyleContext.NamedStyle

    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 JavaBeansTM has been added to the `java.beans` package. Please see `XMLEncoder`.

Field Detail

### listenerList

    protected EventListenerList listenerList

  The change listeners for the model.

### 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".

Constructor Detail

### StyleContext.NamedStyle

    public StyleContext.NamedStyle(String name,
                                   Style parent)
