util
Class Functional.Iteration<T>

java.lang.Object
  util.Functional.Iteration<T>

Type Parameters:

T - The type of object over which to iterate.

All Implemented Interfaces:

Iterable<T>

Enclosing class:

Functional

public static final class Functional.Iteration<T>
extends Object
implements Iterable<T>

An adaptor for iterating in a foreach loop, given an iterator.

(Really, Iterator<T> should be a superinterface of Iterable<T>, or at least iterators ought to be allowed in foreach loops (since the meaning is obvious). Oh well.)

Field Summary

Iterator<T>

iter The iterator iterated over.

Constructor Summary

Functional.Iteration(Iterator<T> iter)
Construct an Iterable for an Iterator.

Method Summary

Iterator<T>	iterator() Get back the iterator passed in to the constructor.
static <T> Functional.Iteration<T>	with(Iterator<T> iter) Convenience constructor (to avoid giving an explicit type).
