<h2>Description</h2>
<div class="description">
<p>The <a href="Poco.Debugger.html" title="class Poco::Debugger">Debugger</a> class provides an interface to the debugger. The presence of a debugger can be checked for, messages can be written to the debugger's log window and a break into the debugger can be enforced. The methods only work if the program is compiled in debug mode (the macro _DEBUG is defined). </p>
</div>
