Subclasses:

DefaultStyledDocument.SectionElement

public class AbstractDocument.BranchElement

extends AbstractDocument.AbstractElement

Implements a composite element that contains other elements.

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 Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.
