Methods Summary
public voidaddDescriptor(java.lang.Object newDescriptor)

param
descriptor the new 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.
