+/**
+ * <em>Functional interfaces</em> provide typing for lambda expressions. Each
+ * functional interface provides a single abstract method to which the lambda
+ * expression's parameter and return types are matched.
+ *
+ * <p>The interfaces in this package are all functional interfaces used with the
+ * collections and streams frameworks. The operation identified by each
+ * interface is generally applied to a collection or stream of objects.
+ *
+ * <p>All functional interface implementations are expected to ensure that:
+ * <ul>
+ * <li>When used for aggregate operations upon many elements it should not be
+ * assumed that the operation will be called upon elements in any specific order.
+ * </li>
+ * <li>{@code null} values are accepted and returned by these functional
+ * interfaces according to the constraints of the specification in which the
+ * functional interfaces are used. The functional interfaces themselves do not
+ * constrain or mandate use of {@code null} values. Most usages of the
+ * functional interfaces will define the role, if any, of {@code null} for that
+ * context.
+ * </li>
+ * </ul>
