Detailed Description
Timer - This class is used to track the amount of time spent between invocations of it's startTimer()/stopTimer() methods. Given appropriate OS support it can also keep track of the RSS of the program at various points. By default, the Timer will print the amount of time it has captured to standard error when the laster timer is destroyed, otherwise it is printed when its TimerGroup is destroyed. Timers do not print their information if they are never started.Definition at line 36 of file Timer.h.

startTimer - Start the timer running. Time between calls to startTimer/stopTimer is counted by the Timer class. Note that these calls must be correctly paired.

| void Timer::addPeakMemoryMeasurement | ( | ) | [static] |
addPeakMemoryMeasurement - This method should be called whenever memory usage needs to be checked. It adds a peak memory measurement to the currently active timers, which will be printed when the timer group prints
