This property map is an adaptor that contains a <a
|
|
href="../../smart_ptr/shared_array.htm">boost::shared_array</a> and uses that
|
|
array to store the property map's data. The resulting property map is a model
|
|
of <a href="./LvaluePropertyMap.html">Lvalue Property Map</a>.
|
|
The <tt>OffsetMap</tt> type is responsible for converting
|
|
key objects to integers that can be used as offsets into the array.
