  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:
    `href` - is the value of an href attribute (or an Attachment id)
  Returns:
    MessageElement other Object or null

### addObjectById

    public void addObjectById(java.lang.String id,

  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.

  Parameters:
    `id` - (id name without the #)
    `obj` - is the deserialized object for this id.

### registerFixup

    public void registerFixup(java.lang.String href,
                              Deserializer 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.

  Parameters:
    `href` - (#id syntax)
    `dser` - is the deserializer of the element

### registerElementByID

    public void registerElementByID(java.lang.String id,
                                    MessageElement 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.

  Parameters:
    `id` - (id name without the #)
    `elem` - is the MessageElement

### registerResolverForID

    public void registerResolverForID(java.lang.String id,
                                      IDResolver resolver)

  Each id can have its own kind of resolver. This registers a resolver for the id.

### hasElementsByID

    public boolean hasElementsByID()

  Return true if any ids are being tracked by this DeserializationContext

  Returns:
    true if any ides are being tracked by this DeserializationContext

### getCurrentRecordPos

  Management of sub-handlers (deserializers)

### replaceElementHandler

    public void replaceElementHandler(SOAPHandler handler)

  Replace the handler at the top of the stack. This is only used when we have a placeholder Deserializer for a referenced object which doesn't know its type until we hit the referent.

### setProcessingRef

    public void setProcessingRef(boolean ref)

### isProcessingRef

    public boolean isProcessingRef()

                            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. (example: when we need to record a long string of events scanning forward in the document to find an element with a particular ID.)

  Specified by:
    `startPrefixMapping` in interface `org.xml.sax.ContentHandler`
