- extends Object
- implements Element, MutableAttributeSet, Serializable, TreeNode
Implements the abstract part of an element. By default elements support attributes by having a field that represents the immutable part of the current attribute set for the element. The element itself implements MutableAttributeSet which can be used to modify the set by fetching a new immutable set. The immutable sets are provided by the AttributeContext associated with the document.
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
