java.lang.Object org.apache.wicket.markup.html.DecoratingHeaderResponse
public abstract class DecoratingHeaderResponse
This is simply a helper implementation of IHeaderResponse that really delegates all of its method calls to the IHeaderResponse that is passed into the constructor. It is defined as abstract because it's only meant to be extended and not used a la carte. You can extend it and override only the methods that you want to change the functionality of.
