| 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. |
| </p> |
