Modifier and Type | Method and Description |
---|---|
Element |
getParent()
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. |
boolean |
isReadOnly()
isReadOnly returns true if this node is read only
and cannot be modified. |
void |
setName(String name)
Sets the text data of this node or this method will
throw an
UnsupportedOperationException if it is
read-only. |
void |
setParent(Element parent)
setParent sets the parent relationship of
this node if the parent relationship is supported or does nothing
if the parent relationship is not supported. |
void |
setText(String text)
sets the value of the entity if it is not defined yet
otherwise an
UnsupportedOperationException is thrown
as this class is read only. |
boolean |
supportsParent()
supportsParent returns true if this node supports the
parent relationship. |

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.

public boolean isReadOnly()
Node
isReadOnly
returns true if this node is read only
and cannot be modified.
Any attempt to modify a read-only Node
will result in
an UnsupportedOperationException
being thrown.
