     * directly enclosing {@code overrider} (the possibly-overriding
     * method).  For example, suppose {@code m1} represents the method

     * {@code m2} within the class {@code String} (it does):

     * A more interesting case can be illustrated by the following example
     * in which a method in type {@code A} does not override a
     * like-named method in type {@code B}:
     *
     * <blockquote>
     * {@code class A { public void m() {} } }<br>

     * ...<br>
     * {@code m1 = ...;  // A.m }<br>

     * {@code assert ! elements.overrides(m1, m2,
     *          elements.getTypeElement("A")); }
     * </blockquote>
     *
     * When viewed as a member of a third type {@code C}, however,
     * the method in {@code A} does override the one in {@code B}:
     *
     * <blockquote>
     * {@code class C extends A implements B {} }<br>
     * ...<br>
     * {@code assert elements.overrides(m1, m2,
     *          elements.getTypeElement("C")); }
     * </blockquote>
     *
     * @param overrider  the first method, possible overrider
     * @param overridden  the second method, possibly being overridden
     * @param type   the type of which the first method is a member
     * @return {@code true} if and only if the first method overrides
