public class AbstractDocument.LeafElement extends AbstractDocument.AbstractElement
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.beanspackage. Please seeXMLEncoder.- See Also:
