Description</h2>This class makes it possible to log information on different abstraction levels. All messages are passed to the log method 'log' with a level indication. When this level lies in the specified range (iMinLogLevel.. iMaxLogLevel) the message is logged, otherwise it is ignored. This makes it possible to print only the information you are interested in. There is one global Log class which is used by all classes that use the Logger. This instantation of the Logger is located in the file <a class="el" href="Logger_8C.html">Logger.C</a> and is called 'Log'. All classes that want use this Logger should make a reference to it using the line 'extern Logger Log;' and can then use this Logger with the Log.log( ... ) methods. Furthermore the Logger also contains a timer with makes it possible to print the time since the timer has been restarted. <p><p>Definition at line <a class="el" href="Logger_8h-source.html#l00094">94</a> of file <a class="el" href="Logger_8h-source.html">Logger.h</a>.<hr><h2>Constructor & Destructor Documentation</h2><a name="a0" doxytag="Logger::Logger"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> Logger::Logger </td> <td class="md" valign="top">( </td> <td class="md" nowrap valign="top">ostream & </td> <td class="mdname" nowrap> <em>o</em> = cout, </td> </tr> <tr> <td></td> <td></td> <td class="md" nowrap>int </td> <td class="mdname" nowrap> <em>iMin</em> = 0, </td> </tr> <tr> <td></td> <td></td> <td class="md" nowrap>int </td> <td class="mdname" nowrap> <em>iMax</em> = 0</td> </tr> <tr> <td></td> <td class="md">) </td> <td class="md" colspan="2"></td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>This is the constructor for the Logger.
