 <h1>MDC Class Reference</h1><!-- doxytag: class="log4cxx::MDC" --><a href="classlog4cxx_1_1_m_d_c-members.html">List of all members.</a><hr><a name="_details"></a><h2>Detailed Description</h2>
 The <a class="el" href="classlog4cxx_1_1_m_d_c.html">MDC</a> class is similar to the <a class="el" href="classlog4cxx_1_1_n_d_c.html">NDC</a> class except that it is based on a map instead of a stack.
 <p>
 It provides <em>mapped diagnostic contexts</em>. A <em>Mapped Diagnostic Context</em>, or <a class="el" href="classlog4cxx_1_1_m_d_c.html">MDC</a> in short, is an instrument for distinguishing interleaved log output from different sources. Log output is typically interleaved when a server handles multiple clients near-simultaneously.<p>
 <b><em>The <a class="el" href="classlog4cxx_1_1_m_d_c.html">MDC</a> is managed on a per thread basis</em></b>. A child thread automatically inherits a <em>copy</em> of the mapped diagnostic context of its parent.
