javax.swing.text.AbstractDocument.AbstractElement
javax.swing.text.AbstractDocument.LeafElement
- All Implemented Interfaces:
Serializable,AttributeSet,Element,MutableAttributeSet,TreeNode
- Direct Known Subclasses:
HTMLDocument.RunElement
- Enclosing class:
- AbstractDocument
Implements an element that directly represents content of
some kind.
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.
