| * Basic functor interfaces. |
| * </p> |
| * <p> |
| * Implementors are encouraged, but not strictly required, to make each functor |
| * implementation {@link java.io.Serializable Serializable}. |
| * </p> |
| * <p> |
| * Note that each functor interface extends the |
| * {@link java.lang.Object#equals Object.equals} contract to state that |
| * <code>equals</code> can return <tt>true</tt> <i>only</i> if |
| * the specified Object implements the same functor interface |
| * and is known to produce the same results and/or side-effects |
| * for the same arguments (if any). Note that the default |
| * <code>Object.equals</code> implementation |
| * does in fact adhere to the functor <code>equals</code> contract. |
