| The above macros generate the necessary code to adapt <code class="computeroutput"><span class="identifier">struct_name</span></code> |
| as a model of <a class="link" href="../sequence/concepts/random_access_sequence.html" title="Random Access Sequence">Random |
| Access Sequence</a> and <a class="link" href="../sequence/concepts/associative_sequence.html" title="Associative Sequence">Associative |
| Sequence</a> while using <code class="computeroutput"><span class="identifier">adapted_name</span></code> |
| as the name of the adapted struct. The sequence <code class="computeroutput"><span class="special">(</span><span class="identifier">namespace0</span><span class="special">)(</span><span class="identifier">namespace1</span><span class="special">)...</span></code> |
| declares the namespace for <code class="computeroutput"><span class="identifier">adapted_name</span></code>. |
| It yields to a fully qualified name for <code class="computeroutput"><span class="identifier">adapted_name</span></code> |
| of <code class="computeroutput"><span class="identifier">namespace0</span><span class="special">::</span><span class="identifier">namespace1</span><span class="special">::...</span> |
| <span class="identifier">adapted_name</span></code>. If an empty namespace |
| sequence is given (that is a macro that expands to nothing), the adapted |
| view is placed in the global namespace. If no namespace sequence is given |
| (i.e. <code class="computeroutput"><span class="identifier">BOOST_FUSION_ADAPT_STRUCT_ASSOC_NAMED</span></code>), |
| the adapted view is placed in the namespace <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">fusion</span><span class="special">::</span><span class="identifier">adapted</span></code>. |
| The sequence of <code class="computeroutput"><span class="special">(</span><span class="identifier">member_typeN</span><span class="special">,</span> <span class="identifier">member_nameN</span><span class="special">,</span> <span class="identifier">key_typeN</span><span class="special">)</span></code> triples declares the type, name and key |
| type of each of the struct members that are part of the sequence. |
| </p> |
| <p> |
| The macros should be used at global scope, and <code class="computeroutput"><span class="identifier">struct_name</span></code> |
| should be the fully namespace qualified name of the struct to be converted. |
