java.lang.Object
- javax.swing.text.SimpleAttributeSet

All Implemented Interfaces:

Serializable, Cloneable, AttributeSet, MutableAttributeSet
```
public class SimpleAttributeSet
extends Object
implements MutableAttributeSet, Serializable, Cloneable
```
A straightforward implementation of MutableAttributeSet using a hash table.
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.
