org.eclipse.nebula.widgets.compositetable.internal.RelaxedDuckType

All Implemented Interfaces:

java.lang.reflect.InvocationHandler

public class RelaxedDuckType
extends DuckType
implements java.lang.reflect.InvocationHandler

RelaxedDuckType. Implements Duck Typing for Java. ("If it walks like a duck, quacks like a duck, it..."). Essentially allows programs to treat objects from separate hierarchies as if they were designed with common interfaces as long as they adhere to common naming conventions.

This version is the relaxed DuckType. If a method in the interface is not present on the underlying object, the proxy simply returns null.
