formatting.</p> 136<p>This stream wrapper is used by the library for log record formatting. It implements the standard string stream interface with a few differences:</p> 137<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> 138<li class="listitem"><p>It does not derive from standard types <code class="computeroutput">std::basic_ostream</code>, <code class="computeroutput">std::basic_ios</code> and <code class="computeroutput">std::ios_base</code>, although it tries to implement their interfaces closely. There are a few small differences, mostly regarding <code class="computeroutput">rdbuf</code> and <code class="computeroutput">str</code> signatures, as well as the supported insertion operator overloads. The actual wrapped stream can be accessed through the <code class="computeroutput">stream</code> methods. </p></li> 139<li class="listitem"><p>By default, <code class="computeroutput">bool</code> values are formatted using alphabetical representation rather than numeric. </p></li> 140<li class="listitem"><p>The stream supports writing strings of character types different from the stream character type. The stream will perform character code conversion as needed using the imbued locale. </p></li> 141<li class="listitem"><p>The stream operates on an external string object rather than on the embedded one. The string can be attached or detached from the stream dynamically.</p></li> 142</ul></div> 143<p> 144Although <code class="computeroutput"><a class="link" href="basic_formatting_ostream.html" title="Class template basic_formatting_ostream">basic_formatting_ostream</a></code> does not derive from <code class="computeroutput">std::basic_ostream</code>, users are not required to add special overloads of <code class="computeroutput">operator<<</code> for it since the stream will by default reuse the operators for <code class="computeroutput">std::basic_ostream</code>. However, one can define special overloads of <code class="computeroutput">operator<<</code> for <code class="computeroutput"><a class="link" href="basic_formatting_ostream.html" title="Class template basic_formatting_ostream">basic_formatting_ostream</a></code> if a certain type needs special formatting when output to log. </p> 145<div class="refsect2"> 146<a name="idm44984859841424"></a><h3> 147<a name="boost.log.basic_formatting_ostreamconstruct-copy-destruct"></a><code class="computeroutput">basic_formatting_ostream</code> 148 public 149 construct/copy/destruct</h3> 150<div class="orderedlist"><ol class="orderedlist" type="1"> 151<li class="listitem"> 152<pre class="literallayout"><a name="idm46079574484208-bb"></a><span class="identifier">basic_formatting_ostream</span><span class="special">(</span><span class="special">)</span><span class="special">;</span></pre> 153<p>Default constructor.
