public Element getParent()
Node
getParent
returns the parent Element
if this node supports the parent relationship or null if it is
the root element or does not support the parent relationship.
This method is an optional feature and may not be supported
for all Node
implementations.

public void setParent(Element parent)
Node
setParent
sets the parent relationship of
this node if the parent relationship is supported or does nothing
if the parent relationship is not supported.
This method should only be called from inside an
Element
implementation method and is not intended for
general use.

parent
- is the new parent of this node.public boolean supportsParent()
Node
supportsParent
returns true if this node supports the
parent relationship.
Some XML tree implementations are singly linked and only support downward navigation through children relationships. The default case is that both parent and children relationships are supported though for memory and performance reasons the parent relationship may not be supported.
