Constructors Summary
Methods Summary
public java.lang.ObjectgetDescriptor()

return
the descriptor instance to associate with this XMLNode

        return descriptor;
protected java.util.MapgetDispatchTable()
all sub-implementation of this class can use a dispatch table to map xml element to method name on the descriptor class for setting the element value.

return
the map with the element name as a key, the setter method as a value

    
        Map table = super.getDispatchTable();
        table.put(RuntimeTagNames.JNDI_NAME, "setJndiName");
        return table;
public voidsetElementValue(com.sun.enterprise.deployment.node.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

param
the descriptor to write
return
