See
NullObject.
Sometimes you will not want a
NullObject to do nothing at all - just not to do something in particular. Or is this another pattern? --

You are absolutely right. Very often,
NullObjects do something, rather than nothing. They tend to implement "default" behaviour, which is the reason why I tend to refer to this as the
DefaultObject pattern. --
