org.eclipse.persistence.internal.oxm.record.deferred.CompositeObjectMappingContentHandler

All Implemented Interfaces:

ExtendedContentHandler, org.xml.sax.ContentHandler, org.xml.sax.ext.LexicalHandler

public class CompositeObjectMappingContentHandler
extends CompositeMappingContentHandler

INTERNAL:

Purpose: An implementation of DeferredContentHandler used to queue events to enable state-specific behavior for simple, complex or empty elements.

Responsibilities:

Null Composite Objects are marshalled in 2 ways when the input XML node is empty. (1) as null - isNullRepresentedByEmptyNode = true (2) as empty object - isNullRepresentedByEmptyNode = false A deferred contentHandler is used to queue events until we are able to determine whether we are in one of empty/simple/complex state. Control is returned to the UnmarshalHandler after creation of (1) or (2) above is started.
