public interface ReferenceResolver

Interface for classes that can resolve external or internal references.

Method Summary

void	addReferenceElement(java.lang.String id, org.w3c.dom.Node element) Add a reference node for the given refid.
java.lang.Object	resolveReference(GraphMLParseContext context, java.lang.String refid, DeserializationHandler deserializer) Resolve an xml node to an object instance.

Method Detail

addReferenceElement

public void addReferenceElement(java.lang.String id,
                                org.w3c.dom.Node element)

Add a reference node for the given refid.

Parameters:

id - The reference id

element - DOM node that is referenced by the id.

resolveReference

public java.lang.Object resolveReference(GraphMLParseContext context,
                                         java.lang.String refid,
                                         DeserializationHandler deserializer)
                                  throws GraphMLParseException

Resolve an xml node to an object instance.

This method returns shared instances for nodes with the same refid.

Parameters:

context - The current parse context.

refid - The refid which should be resolved. Must not be null.

deserializer - Deserializer which should be used for deserialization of the shared element. Can be null when not called from a deserializer instance, in which case the resolver tries to find a matching deserializer itself.

Returns:

the referenced object

Throws:

GraphMLParseException
