Constructor Summary

DVMCharDataNode(String value)
Creates a CHARDATA node with the specified value.

DVMCharDataNode(String value, Locator loc, boolean isShared)
Creates a CHARDATA node and sets its associated locator and isShared status.

Method Summary

boolean	equals(Object o) Only equal if object is a Node with the same type and same value.
String	getAttribute(String attrName) Always null.
String[]	getAttributeNames() Empty array.
List<Attribute>	getAttributes() Empty list.
List<SystemNode>	getChildren() Empty list.
String	getNodeValue() Returns the character data of this CHARDATA node.
int	hashCode() Recursively computes a hash code based on the node type, node value, attributes, and children.
void	setChild(int index, SystemNode child) Throws an IllegalArgumentException since CHARDATA nodes cannot have children.
