public interface Node
extends Node

A representation of a node (element) in a DOM representation of an XML document that provides some tree manipulation methods. This interface provides methods for getting the value of a node, for getting and setting the parent of a node, and for removing a node.

Method Summary

Modifier and Type	Method and Description
void	detachNode() Removes this Node object from the tree.
SOAPElement	getParentElement() Returns the parent element of this Node object.
String	getValue() Returns the the value of the immediate child of this Node object if a child exists and its value is text.
void	recycleNode() Notifies the implementation that this Node object is no longer being used by the application and that the implementation is free to reuse this object for nodes that may be created later.
void	setParentElement(SOAPElement parent) Sets the parent of this Node object to the given SOAPElement object.
void	setValue(String value) If this is a Text node then this method will set its value, otherwise it sets the value of the immediate (Text) child of this node.

Method Detail

getValue

String getValue()

Returns the the value of the immediate child of this Node object if a child exists and its value is text.

Returns:

a String with the text of the immediate child of this Node object if (1) there is a child and (2) the child is a Text object; null otherwise

setParentElement

void setParentElement(SOAPElement parent)
               throws SOAPException

Sets the parent of this Node object to the given SOAPElement object.

Parameters:

parent - the SOAPElement object to be set as the parent of this Node object

Throws:

SOAPException - if there is a problem in setting the parent to the given element

See Also:

getParentElement()

getParentElement

SOAPElement getParentElement()

Returns the parent element of this Node object. This method can throw an UnsupportedOperationException if the tree is not kept in memory.

Returns:

the SOAPElement object that is the parent of this Node object or null if this Node object is root

Throws:

UnsupportedOperationException - if the whole tree is not kept in memory

See Also:

setParentElement(javax.xml.soap.SOAPElement)

detachNode

void detachNode()

Removes this Node object from the tree. Once removed, this node can be garbage collected if there are no application references to it.

recycleNode

void recycleNode()

Notifies the implementation that this Node object is no longer being used by the application and that the implementation is free to reuse this object for nodes that may be created later.

Calling the method recycleNode implies that the method detachNode has been called previously.

setValue

void setValue(String value)

If this is a Text node then this method will set its value, otherwise it sets the value of the immediate (Text) child of this node. The value of the immediate child of this node can be set only if, there is one child node and that node is a Text node, or if there are no children in which case a child Text node will be created.

Parameters:

value - the text to set

Throws:

IllegalStateException - if the node is not a Text node and either has more than one child node or has a child node that is not a Text node
