/PROPOSAL 1/ Additions to IteratorUtils

[Lee Crawford]

I'd like to propose the following simple additions to the
o.a.c.c.IteratorUtils
class. 

The following is a simple convenience method for counting the number of
elements
in an iteration, something that I find myself recreating somewhat
frequently: 

  public static
  int countElements (final Iterator iter) {
    int cnt = 0; 
    while (iter.hasNext ()) { 
      cnt ++; 
    }
    return cnt; 
  }

There isn't an EnumeratorUtils present that might contain an equivalent:


  public static
  int countElements (final Enumerator enum) {
    int cnt = 0; 
    while (enum.hasNext ()) { 
      cnt ++; 
    }
    return cnt; 
  }

Or the slightly less performant: 

  public static
  int countElements (final Enumerator enum) {
    return IteratorUtils.countElements (asIterator (enum)); 
  }

Thoughts?
