Class NodeFactory

java.lang.Object
oracle.xml.parser.v2.NodeFactory

All Implemented Interfaces:

java.io.Serializable

public class NodeFactory

extends java.lang.Object

implements java.io.Serializable

This class specifies methods to create various nodes of the DOM tree built during parsing. Applications can override these methods to create their own custom classes to be added to the DOM tree while parsing. Applications have to register their own NodeFactory using the DOMParser's setNodeFactory() method. If a null pointer is returned by these methods, then the node will not be added to the DOM tree.

Constructor Detail

NodeFactory

public NodeFactory()

Default constructor for NodeFactory

NodeFactory

protected NodeFactory(XMLDocument doc)

Constructor for NodeFactory to setup Document context

Parameters:

doc - - Document used to create node, if the function is not present in the subclass.

Method Detail

isNamespaceAware

public boolean isNamespaceAware()

Check if the NodeFactory is namespace aware If TRUE, createElementNS(localName, prefix, namespaceURI) and createAttributeNS(localName, prefix, namespaceURI, value) functions will be used to create Element and Attr nodes. The default is FALSE, to keep backward compatibilty. Subclasses must override this function and return 'true' to create namespace aware nodes.

Returns:

- boolean - namespace awareness

createDocument

public XMLDocument createDocument()

Creates a document node. This method cannot return a null pointer.

Returns:

The created document

createElement

public XMLElement createElement(java.lang.String tag)

Creates an Element node with the specified tag.

Parameters:

tag - The name of the element.

Returns:

The created element.

public XMLElement createElementNS(java.lang.String localName,
                                  java.lang.String prefix,
                                  java.lang.String namespaceURI)

Creates an Element node with the specified local name,prefix , namespaceURI.

Parameters:

localName - the name of the element

prefix - the prefix of the element,

namespaceURI - the namespace of the element

Returns:

The created element.

createTextNode
