Hm...
org.apache.commons.collections.bag.HashBag bag
= new org.apache.commons.collections.bag.HashBag();
bag.add("a");
System.out.println(bag.getCount("a"));
bag.add("a");
System.out.println(bag.getCount("a"));
bag.remove("a");
System.out.println(bag.getCount("a"));
bag.remove("a");
System.out.println(bag.getCount("a"));
gives
1
2
0
0
but I'd expect
1
2
1
0
this is because the remove(obj) is not
delegating to a remove(obj,1) but is
a full remove. ...so I have to extend
that class.
IMO having
remove(obj) -> remove(obj,1)
removeAll(obj)
removeAll()
would make more sense.
My 2 cents
cheers
