Methods Summary
public voidaddDescriptor(java.lang.Object newDescriptor)
Adds a new DOL descriptor instance to the descriptor instance associated with this XMLNode

param
descriptor the new descriptor

        if (newDescriptor instanceof MethodDescriptor) {
            methods.add(newDescriptor);
        }
public booleanendElement(XMLElement element)
receives notification of the end of an XML element by the Parser

param
element the xml tag identification
return
true if this node is done processing the XML sub tree

        boolean doneWithNode = super.endElement(element);

            }
        }        
        return doneWithNode;
public java.lang.ObjectgetDescriptor()

return
the Descriptor subclass that was populated by reading the source XML file

        return null;
public voidsetElementValue(XMLElement element, java.lang.String value)
receives notiification of the value for a particular tag

param
element the xml element
param
value it's associated value

write the descriptor class to a DOM tree and return it

param
parent node in the DOM tree
param
node name for the root element of this xml fragment
param
the descriptor to write
return
the DOM tree top node
