/**

|
|
* returned by calls to next() (e.g. for values, and Map.Entry

|
* objects).
|

|
* <p> Note that iteration is fastest if you forego the calls to
|
|
* <tt>hasNext</tt> in favor of checking the size of the structure
|
|
* yourself and then call next() that many times:

|
* <p/>
|
|
* <pre>
|
|
* Iterator i = collection.iterator();
|
|
* for (int size = collection.size(); size-- > 0;) {
|
|
* Object o = i.next();
|
|
* }
|
|
* </pre>
|
|
* <p/>
|
|
* <p>You may, of course, use the hasNext(), next() idiom too if
|
|
* you aren't in a performance critical spot.</p>
