  26  * <em>Functional interfaces</em> provide typing for lambda expressions. Each

  28  * expression's parameter and return types are matched.
  29  *
  30  * <p>The interfaces in this package are all functional interfaces used with the
  31  * collections and streams frameworks. The operation identified by each
  32  * interface is generally applied to a collection or stream of objects.
  33  *
  34  * <p>All functional interface implementations are expected to:
  35  * <ul>
  36  * <li>When used for aggregate operations upon many elements it should not be
  37  * assumed that the operation will be called upon elements in any specific order.
  38  * </li>
