The central component of the library is the <code class="computeroutput"><a class="link" href="../boost/property_tree/basic_ptree.html" title="Class template basic_ptree">basic_ptree</a></code>
class template. Instances of this class are property trees. It is parametrized
on key and data type, and key comparison policy; <code class="computeroutput"><a class="link" href="../boost/property_tree/ptree.html" title="Type definition ptree">ptree</a></code>,
<code class="computeroutput"><a class="link" href="../boost/property_tree/wptree.html" title="Type definition wptree">wptree</a></code>, <code class="computeroutput"><a class="link" href="../boost/property_tree/iptree.html" title="Type definition iptree">iptree</a></code> and <code class="computeroutput"><a class="link" href="../boost/property_tree/wiptree.html" title="Type definition wiptree">wiptree</a></code>
are typedefs of <code class="computeroutput"><a class="link" href="../boost/property_tree/basic_ptree.html" title="Class template basic_ptree">basic_ptree</a></code>
using predefined combinations of template parameters. Property tree is basically
a somewhat simplified standard container (the closest being std::list), plus
a bunch of extra member functions. These functions allow easy and effective
access to the data stored in property tree. They are various variants of <code class="computeroutput"><a class="link" href="../boost/property_tree/basic_ptree.html#idm45507104765184-bb">get</a></code>, <code class="computeroutput"><a class="link" href="../boost/property_tree/basic_ptree.html#idm45507098260000-bb">put</a></code>, <code class="computeroutput"><a class="link" href="../boost/property_tree/basic_ptree.html#idm45507046494640-bb">get_value</a></code>,
<code class="computeroutput"><a class="link" href="../boost/property_tree/basic_ptree.html#idm45507047391488-bb">put_value</a></code>,
<code class="computeroutput"><a class="link" href="../boost/property_tree/basic_ptree.html#idm45506983002336-bb">get_child</a></code>,
<code class="computeroutput"><a class="link" href="../boost/property_tree/basic_ptree.html#idm45507097758848-bb">put_child</a></code>.
Additionally, there is a <code class="computeroutput"><a class="link" href="../boost/property_tree/basic_ptree.html#idm45506983006304-bb">data</a></code>
function to access node data directly.
