Method Summary | |
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 |
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 |
setValue(java.lang.String value)
Sets the value of this attribute or this method will throw an UnsupportedOperationException if it is
read-only. |
boolean |
supportsParent()
supportsParent returns true if this node supports the
parent relationship. |

public void setValue(java.lang.String value)
Attribute
Sets the value of this attribute or this method will
throw an UnsupportedOperationException
if it is
read-only.
setValue

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.
getParent
in interface Node
getParent
in class AbstractNode
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.
setParent
in interface Node
setParent
in class AbstractNode
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.
supportsParent
in interface Node
supportsParent
in class AbstractNode
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.

isReadOnly
in class AbstractNode
