<h3 class="fn"><a name="const_iterator"></a>const_iterator::const_iterator ()</h3>

<p>Constructs an uninitialized iterator.</p>

<p>Functions like operator*() and operator++() should not be called on an uninitialized iterator. Use operator=() to assign a value to it before using it.</p>

<p>Constructs a copy of <i>other</i>.</p>

<h3 class="fn"><a name="const_iterator-4"></a>const_iterator::const_iterator ( const <a href="qlist-iterator.html">iterator</a> & <i>other</i> )</h3>

<p>Constructs a copy of <i>other</i>.</p>

<h3 class="fn"><a name="operator-not-eq"></a>bool const_iterator::operator!= ( const const_iterator & <i>other</i> ) const</h3>

<p>Returns true if <i>other</i> points to a different item than this iterator; otherwise returns false.</p>

<p>See also <a href="qlist-const-iterator.html#operator-eq-eq">operator==</a>().</p>

<h3 class="fn"><a name="operator-2a"></a>const T & const_iterator::operator* () const</h3>
