where does the Editable.append() implemented?
<p>Here is the code :</p>

<pre><code>Editable text = (Editable)mResults.getText();     //mResults is a TextView.
</code></pre>

<p>I want to know, when i call <code>text.append("***")</code>,which implements is called? I can't find where the Editable interface is implemented.</p>
