Class DummyBindingStrategy

java.lang.Object

net.sf.jguiraffe.gui.forms.bind.DummyBindingStrategy

All Implemented Interfaces:

BindingStrategy

public final class DummyBindingStrategy
extends Object
implements BindingStrategy

A dummy implementation of the BindingStrategy interface.

This strategy can be used when no specific (functional) BindingStrategy implementation is available or is needed (for instance as an application of the null object pattern). All methods are implemented as dummies that do not provide any specific functionality - refer to the documentation of the single methods for more details.

It is not possible to create instances of this class. Instead the static INSTANCE field can be used. This instance can be shared between multiple threads.
