NAME

Dancer::Timer - a timer for Dancer

SYNOPSIS

    use Dancer::Timer;

    my $timer = Dancer::Timer->new();
    my $time  = $timer->tick;
    print "[$time]: Doing something\n";

    # (time passes)
    $time = $timer->tick;
    print "[$time]: Doing something else\n";

    # (time passes)
    $time = $timer->to_string;
    print "[$time]: Doing another thing\n";

DESCRIPTION

Dancer::Timer provides Dancer with a timing object to clock operations. For example, you might want a logging that shows you when each operation happened (at what time) to determine how long each operation was in order to know where to focus on for possible bugs or perhaps unnecessary slowness.

Dancer uses Dancer::Timer in facilities that want to provide this for you. Any plugin author is more than welcome to use it as well.

ATTRIBUTES

start_time

Retains the starting time of the timer. The default value is when the object is created. It fetches that using gettimeofday from Time::HiRes.

METHODS

init

This method is called when ->new() is called. It initializes the start_time attribute.

tick

Creates a tick in the timer and returns the interval between the start_time and now.

to_string

Same as tick, just more expressive.
