<p>Local and remote tracing. </p>
<p><a class="el" href="classgbxutilacfr_1_1Tracer.html" title="Local and remote tracing.">Tracer</a> is used to log human-readable trace statements, e.g. warnings, error messages, etc (not data).</p>
<p>A single <a class="el" href="classgbxutilacfr_1_1Tracer.html" title="Local and remote tracing.">Tracer</a> object is meant to be shared by multiple threads, so the implementation must be thread-safe.</p>
<p>When the tracing message is cheap to generate, simply call one of the tracing functions. The routing to destinations will be performed internally.</p>
<div class="fragment"><pre class="fragment">
//! std::string s = "something is wrong";
//! tracer->error( s );
//! </pre></div><p>If the tracing message is a result of an expensive operation, you many want to perform the tracing test yourself and then call the tracing function. You may test verbosity for specific TraceType / DestinationType combinations or use summary fields AnyTrace and ToAny.</p>
