Constructor that starts the timer.
Definition: Timer.h:30
void start(const std::string &msg, std::ostream &os=std::cerr)
Start the timer.
Definition: Timer.h:35
auto elapsed()
call record and return the elapsed time (since start) in miliseconds
Definition: Timer.h:55
Definition: GridHandle.h:27
void stop(std::ostream &os=std::cerr)
stop the timer and print elapsed time to a stream
Definition: Timer.h:65
void record()
Record the stop time so the elapsed time since start can be computed.
Definition: Timer.h:42
Timer()
Default constructor.
Definition: Timer.h:25
void restart(const std::string &msg, std::ostream &os=std::cerr)
stop and start the timer again
Definition: Timer.h:86
float milliseconds() const
Returns the time in milliseconds since record was called.
