Class CowSet<E>

java.lang.Object
  ch.bind.philib.util.CowSet<E>

public final class CowSet<E>
extends Object

A simple implementation of a copy-on-write set.
There are two modification methods: add(Object) and remove(Object)
and two read methods: getView() and isEmpty()
Every modification through the add(Object) or remove(Object) methods and a return value of true will update the view.
The view is shared among all clients and must therefore not be modified!
The modification methods are not optimized for speed since the intent of this cow-list is to guarantee fast reads.
