Examples of net.sf.cglib.proxy.Factory

net.sf.cglib.proxy.Factory
All enhanced instances returned by the {@link Enhancer} class implement this interface.Using this interface for new instances is faster than going through the Enhancer interface or using reflection. In addition, to intercept methods called during object construction you must use these methods instead of reflection. @author Juozas Baliuka baliuka@mwm.lt @version $Id: Factory.java,v 1.13 2004/06/24 21:15:20 herbyderby Exp $
