  +--net.sf.saffron.util.BarfingInvocationHandler

All Implemented Interfaces:

InvocationHandler

Direct Known Subclasses:

SqlNode.DatabaseMetaDataInvocationHandler

public class BarfingInvocationHandler

extends Object

implements InvocationHandler

A class derived from BarfingInvocationHandler handles a method call by looking for a method in itself with identical parameters. If no such method is found, it throws UnsupportedOperationException.

It is useful when you are prototyping code. You can rapidly create a prototype class which implements the important methods in an interface, then implement other methods as they are called.
