what's the meaning of *&
<p>I am a java coder and not familar with the c++ language.
But right now,i read the following code:</p>

<pre><code>void method(A* a,A*&amp; b);

A *a;
A *b;
method(a,b);
</code></pre>

<p>And my question is:
what's the meaning of "*&amp;"?Does it means that it represent the value of b itself?
thx </p>
