|
|
<p>
|
|
A Forward Sequence is a <a href="./Sequence.html">Sequence</a> which guarantees that its elements are arranged in a definite order, and that the ordering will not change spontaneously [<a href="#1">1</a>]. Iterators into a forward sequence satisfy the <a href="./Forward_Iterator.html">Forward Iterator</a> requirements.

<h3>Refinement of</h3>

<a href="./Sequence.html">Sequence</a>

<p>
|
|
<h3>Valid expressions</h3>
|
|
<p>
|
|
Forward Sequence does not define any new expressions beyond those defined in <a href="./Sequence.html">Sequence</a>. However, it refines the expression requirements.

<table border="1">
|
|
<tr><th> Expression </th><th> Expression type </th></tr>
|
|
<tr><td><code>typename begin<s>::type</code></td><td>A model of <a href="./Forward_Iterator.html">Forward Iterator</a> </td></tr>
|
|
<tr><td><code>typename end<s>::type</code></td><td>A model of <a href="./Forward_Iterator.html">Forward Iterator</a> </td></tr>
|
|
</table>

|
<h3>Invariants</h3>
|
|
<p>
|
|
For any forward sequence <code>s</code> the following invariants always hold:
|
|
<ul>
|
|
<li>Two different iterations through <code>s</code> will access its elements in the same order.
|
|
</ul>
|
|
<p>
|
|
<h3>Models</h3>
|
|
<p>
|
|
<ul>
|
|
<li><code><a href="./Reference/vector.html">vector</a></code>
|
|
<li><code><a href="./Reference/vector_c.html">vector_c</a></code>
|
|
<li><code><a href="./Reference/list.html">list</a></code>
|
|
<li><code><a href="./Reference/list_c.html">list_c</a></code>
|
|
<li><code><a href="./Reference/range_c.html">range_c</a></code>
|
|
</ul>
