    <p>I am trying to bind a read handler, and boost asio is driving me crazy.</p> <p>I have the following class</p> <pre><code>class namenode_registration: public boost::enable_shared_from_this&lt;namenode_registration&gt;, private boost::noncopyable { private: [...] public: namenode_registration(....); [...] void handle_request_sent(const boost::system::error_code&amp; e); void handle_read_reply_type(boost::asio::mutable_buffers_1&amp; buffer, const boost::system::error_code&amp; e, std::size_t bytes_transferred); }; </code></pre> <p>With the following implementation :</p> <pre><code>void namenode_registration::handle_request_sent( const boost::system::error_code&amp; e) { if (!e) { boost::asio::async_read(socket_, boost::asio::buffer(buffer_data_, namenode::reply::type_size), boost::bind(&amp;namenode_registration::handle_read_reply_type, shared_from_this(), boost::asio::placeholders::error, boost::asio::placeholders::bytes_transferred)); } } </code></pre> <p>And I really can't understand why it does not compile : </p> <pre><code>In file included from /usr/include/boost/bind.hpp:22:0, from /home/.../datanode/namenode_registration.cpp:9: /usr/include/boost/bind/bind.hpp: In instantiation of ‘boost::_bi::result_traits&lt;boost::_bi::unspecified, void (datanode::namenode_registration::*)(boost::asio::mutable_buffers_1&amp;, const boost::system::error_code&amp;, long unsigned int)&gt;’: /usr/include/boost/bind/bind_template.hpp:15:48: instantiated from ‘boost::_bi::bind_t&lt;boost::_bi::unspecified, void (datanode::namenode_registration::* (boost::asio::mutable_buffers_1&amp;, const boost::system::error_code&amp;, long unsigned int), boost::_bi::list3&lt;boost::_bi::value&lt;boost::shared_ptr&lt;datanode::namenode_registration&gt; &gt;, boost::arg&lt;1&gt; (*)(), boost::arg&lt;2&gt; (*)()&gt; &gt;’ /home/.../datanode/namenode_registration.cpp:50:51: instantiated from here /usr/include/boost/bind/bind.hpp:69:37: erreur: ‘void (datanode::namenode_registration::*)(boost::asio::mutable_buffers_1&amp;, const boost::system::error_code&amp;, long unsigned int)’ is not a class, struct, or union type </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
