Deprecated. The design of this class is misguided, it is better to use SAX, and SAXTraverser. Will be removed from future FreeHEP releases

public abstract class XMLNodeTraverser

extends Object

Utility class for traversing XML DOM trees. This is an abstract class that has methods which are called as different elements are located in a DOM tree. It is designed to be extended for each nore in a specific DOM tree, with its methods overriden to handle specific elements and attributes of the tree.

Method Detail

traverse

public void traverse(Node node)
              throws XMLNodeTraverser.BadXMLException

Deprecated.

Traverse a node

Parameters:

node - The node to traverse

Throws:

XMLNodeTraverser.BadXMLException

handleSubNode

protected void handleSubNode(Node node,
                             String name)
                      throws XMLNodeTraverser.BadXMLException

Deprecated.

Called to handle a subnode of the node being traversed. The default implementation calls handleElement, handleTextNode or handleOtherNode as appropriate.

Parameters:

node - The subnode being handled

name - The name of the subnode

Throws:

XMLNodeTraverser.BadXMLException

handleElementAttributes

protected void handleElementAttributes(NamedNodeMap nnm)
                                throws XMLNodeTraverser.BadXMLException

Deprecated.

Called to handle the attributes associated with the element being traversed. The default implementation calls handleAttributeNode for each attribute

Parameters:

nnm - The attrinbutes being handled

Throws:

XMLNodeTraverser.BadXMLException

handleElement

protected void handleElement(Element node,
                             String name)
                      throws XMLNodeTraverser.BadXMLException

Deprecated.

Handle an Element subnode. The default implementation throws an exception.

Parameters:

node - The element being handled

name - The name of the element

Throws:

XMLNodeTraverser.BadXMLException

handleTextNode

protected void handleTextNode(Text node,
                              String name)
                       throws XMLNodeTraverser.BadXMLException

Deprecated.

Handle a text node. The default implementation does nothing

Throws:

XMLNodeTraverser.BadXMLException

handleAttributeNode

protected void handleAttributeNode(Attr node,
                                   String name,
                                   String value)
                            throws XMLNodeTraverser.BadXMLException

Deprecated.

Handle an element attribute. The default implementation throws an exception

Parameters:

node - The attribute being handled

name - The name of the attribute

value - The value of the attribute

Throws:

XMLNodeTraverser.BadXMLException

handleOtherNode

protected void handleOtherNode(Node node,
                               String name)
                        throws XMLNodeTraverser.BadXMLException

Deprecated.

Handle a node other than an Element or TextNode. The default implementation throws an exception

Parameters:

node - The node being handled

name - The name of the node

Throws:

XMLNodeTraverser.BadXMLException

toInt

public int toInt(String value)
          throws XMLNodeTraverser.BadXMLException

Deprecated.

Utility routine to convert a String to an int

Throws:

XMLNodeTraverser.BadXMLException

getAttributeValue

public String getAttributeValue(String name)

Deprecated.

Convenience method to get the value of some attribute. Note, this will always return null if called while the traverse method is not active. Returns null if the attribute does not exist.

toBoolean

                  throws XMLNodeTraverser.BadXMLException

Deprecated.

Utility routine to convert a String to a boolean

Throws:
