NAME RHP::Timer - A high resolution timer abstraction SYNOPSIS use RHP::Timer (); use My::Logger (); $logger = My::Logger->new; $timer = RHP::Timer->new(); # timing data from the point of the caller $timer->start('fizzbin'); fizzbin(); # how fast is fizzbin? $logger->info( sprintf("Timing caller: %s %s %d, timer_name: %s, time: %s", @{$timer->checkpoint})); # or simpler $timer->start('foobin'); foobin(); $logger->info("pid $$ timer " . $timer->current . " took " . $timer->stop . " seconds"); # what was the last timing block? $logger->info("Last timing block " . $timer->current . " took " . $timer->last_interval . " seconds"); DESCRIPTION RHP::Timer is a wrapper around Time::HiRes. I wrote it because I needed some simple abstractions for timing programs to determine bottlenecks in running programs. The goals of RHP::Timer is to be easy to use, accurate, and simple. METHODS new() $timer = RHP::Timer->new(); Constructor which takes no arguments and returns a timer object start() $timer->start('fizzbin'); Starts the timer for 'fizzbin' stop() $interval = $timer->stop; Stops the last timer started, and returns the number of seconds between start and stop. current() $timer_name = $timer->current(); # $timer_name is 'fizzbin' from previous pod Returns the name of the most recent timer started. checkpoint() [ caller(), $timer_name, $interval ] = $timer->checkpoint(); Stops the current timer and returns an array reference containing caller() information, the name of the timer stopped, and the interval of the last timing run. Useful for passing to a logfile in sprintf or other format. last_interval() $last_interval = $timer->last_interval; Returns the last timing interval recorded by the timer object. BUGS None known yet.
