java: copy-on-write data structure?
- by Jason S
Is there anything in Java that implements something like the following
interface MSet<T> extends Iterable<T> {
/**
* return a new set which consists of this set plus a new element.
* This set is not changed.
*/
MSet<T> add(T t);
/**
* return a new set which consists of this set minus a designated element.
* This set is not changed.
*/
MSet<T> remove(T t);
}
