Methods Summary
public java.lang.ObjectgetDescriptor()

return
the descriptor instance to associate with this XMLNode

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
