  - getElementByID
```
public MessageElement getElementByID(java.lang.String id)
```
    Get the MessageElement for the indicated id (where id is the #value of an href) If the MessageElement has not been processed, the MessageElement will be returned. If the MessageElement has been processed, the actual object value is stored with the id and this routine will return null.
    
    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:
    
    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,
                          java.lang.Object obj)
```
    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

```
public void replaceElementHandler(SOAPHandler handler)

    Record the current set of prefix mappings in the nsMappings table. !!!
