Parameters:
id - is the value of an href attribute
Returns:
MessageElement or null

getObjectByRef

public java.lang.Object getObjectByRef(java.lang.String href)
Gets the MessageElement or actual Object value associated with the href value. The return of a MessageElement indicates that the referenced element has not been processed. If it is not a MessageElement, the Object is the actual deserialized value. In addition, this method is invoked to get Object values via Attachments.

Parameters:

Returns:
MessageElement other Object or null

Add the object associated with this id (where id is the value of an id= attribute, i.e. it does not start with #). This routine is called to associate the deserialized object with the id specified on the XML element.

Specified by:
addObjectById in interface DeserializationContext (src)
Parameters:

obj - is the deserialized object for this id.

registerFixup

public void registerFixup(java.lang.String href,
                          Deserializer (src)  dser)
During deserialization, an element with an href=#id may be encountered before the element defining id=id is read. In these cases, the getObjectByRef method above will return null. The deserializer is placed in a table keyed by href (a fixup table). After the element id is processed, the deserializer is informed of the value so that it can update its target(s) with the value.

Specified by:
registerFixup in interface DeserializationContext (src)
Parameters:
href - (#id syntax)
dser - is the deserializer of the element

registerElementByID

public void registerElementByID(java.lang.String id,
                                SOAPElementAxisImpl (src)  elem)
Register the MessageElement with this id (where id is id= form without the #) This routine is called when the MessageElement with an id is read. If there is a Deserializer in our fixup list (described above), the 'fixup' deserializer is given to the MessageElement. When the MessageElement is completed, the 'fixup' deserializer is informed and it can set its targets.

Specified by:
registerElementByID in interface DeserializationContext (src)
Parameters:
id - (id name without the #)
elem - is the MessageElement

registerResolverForID

                        throws org.xml.sax.SAXException
Record the current set of prefix mappings in the nsMappings table.

!!! We probably want to have this mapping be associated with the MessageElements, since they may potentially need access to them long after the end of the prefix mapping here.
