<span>测试一种方法，作为给定类型的成员，覆盖其他方法。</span>
<span>当非抽象方法覆盖抽象方法时，前者也被<i>称为</i>实现后者。</span>
<p> <span>在最简单和最典型的用法中， <code>type</code>参数的值将简单地是直接包含在<code>overrider</code> （可能覆盖的方法）的类或接口。</span> <span>例如，假设<code>m1</code>表示方法<code>String.hashCode</code> ，而<code>m2</code>表示<code>Object.hashCode</code> 。</span> <span>然后，我们可以问是否<code>m1</code>覆盖<code>m2</code>类中<code>String</code> （它）：</span> </p>
<blockquote>
<span><code>assert elements.overrides(m1, m2, elements.getTypeElement("java.lang.String")); </code></span>
</blockquote>
<span>更有趣的情况下，可以通过下面的例子，其中在类型的方法来说明<code>A</code>不类型覆盖一个类似命名方法<code>B</code> ：</span>
<blockquote>
<span><code>class A { public void m() {} } </code> <br/> <code>interface B { void m(); } </code> <br/> ... <br/> <code>m1 = ...; // A.m </code> <br/> <code>m2 = ...; // B.m </code> <br/> <code>assert ! elements.overrides(m1, m2, elements.getTypeElement("A")); </code></span>
</blockquote>
<span>当作为第三类型的成员观看<code>C</code> ，然而，在该方法<code>A</code>并覆盖一个在<code>B</code> ：</span>
<blockquote>
<span><code>class C extends A implements B {} </code> <br/> ... <br/> <code>assert elements.overrides(m1, m2, elements.getTypeElement("C")); </code></span>
