<p>In this section we'll walk through the implementation of a few
iterators using <tt class="literal"><span class="pre">iterator_facade</span></tt>, based around the simple
example of a linked list of polymorphic objects.</p>
</div>
<div class="section" id="the-problem">
<h2><a class="toc-backref" href="#id15" name="the-problem">The Problem</a></h2>
<p>Say we've written a polymorphic linked list node as follows:</p>
<pre class="literal-block">
# include &lt;iostream&gt;
struct node_base
{
node_base() : m_next(0) {}
virtual ~node_base() { delete m_next; }
node_base* next() const { return m_next; }
// print to the stream
virtual void print(std::ostream&amp; s) const = 0;
// double the value
virtual void twice() = 0;
void append(node_base* p)
{
if (m_next)
m_next-&gt;append(p);
else
m_next = p;
}
private:
node_base* m_next;
};
</pre>
<p>Lists can hold objects of different types by linking together
specializations of the following template:</p>
<pre class="literal-block">
template &lt;class T&gt;
struct node : node_base
{
node(T x)
: m_value(x)
{}
void print(std::ostream&amp; s) const { s &lt;&lt; this-&gt;m_value; }
void twice() { m_value += m_value; }
private:
T m_value;
};
</pre>
<p>And we can print any node using the following streaming operator:</p>
<pre class="literal-block">
inline std::ostream&amp; operator&lt;&lt;(std::ostream&amp; s, node_base const&amp; n)
{
n.print(s);
return s;
}
