public interface Node
extends org.w3c.dom.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

abstract void
detachNode()
Removes this Node object from the tree.
abstract SOAPElement
getParentElement()
Returns the parent element of this Node object.
abstract String
getValue()
Returns the the value of the immediate child of this Node object if a child exists and its value is text.
abstract 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.
abstract void
setParentElement(SOAPElement parent)
Sets the parent of this Node object to the given SOAPElement object.
abstract 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 Details

detachNode

public abstract 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.

getParentElement

public abstract 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

getValue

public abstract 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

recycleNode

public abstract 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.


setParentElement

public abstract 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

setValue

public abstract 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
