What is the origin of "mThis"?
<p>We have some devs on Android part of our application who actively use prefixing of class member variables with "m*".</p>

<p>What is the origin of "mThis" which is basically:</p>

<pre><code>class SomeClass {
    private final SomeClass mThis;
    SomeClass() {
        mthis = this;
    }
}
</code></pre>

<p>and this notation in general?</p>
