Hello
I have to remember some Objects. Each of them is referenced by a key.
The Objects can be 'enabled' or 'disabled' but they shouldn't know about
this state, nor about the key, so I didn't want to put this information
inside of the objects. My wish is like swapping objects in and out.
First I thought of having two Collections, one with the enabled objects
and one with the disabled.
Then I thought of putting all objects in one Dictionary and access them
by two MappedCollections of enabled and disabled objects but AFAIK those
MappedCollections cannot grow or shrink.
Do you have a good idea? Is there a fast way of swapping and accessing them?
thanks
