public abstract class NodeValue
extends Object

INTERNAL:

Purpose: A NodeValue is responsible for performing the unmarshal and marshal operation at a mapping or policy level. The operations are based on a SAX ContextHandler.

Responsibilities:

• Maintain a reference to the owning XPathNode.
• Given a XPathFragment recognize the node to which the mapping should be applied.
• Perform the unmarshal and marshal operation for the given mapping or policy.
