Constructor Detail

DOMBuilder

public DOMBuilder()

Construct a new instance of this DOMBuilder.

DOMBuilder

public DOMBuilder(SAXTransformerFactory factory)

Construct a new instance of this DOMBuilder.

DOMBuilder

public DOMBuilder(DOMBuilder.Listener listener)

Construct a new instance of this DOMBuilder.

DOMBuilder

public DOMBuilder(Node parentNode)

Constructs a new instance that appends nodes to the given parent node.
Note: You cannot use a Listener when appending to a Node, because the notification occurs at endDocument() which does not happen here.

DOMBuilder

public DOMBuilder(DOMBuilder.Listener listener,
                  Node parentNode)

Construct a new instance of this DOMBuilder.

DOMBuilder

public DOMBuilder(SAXTransformerFactory factory,
                  DOMBuilder.Listener listener,
                  Node parentNode)

Construct a new instance of this DOMBuilder.
