NAME

       "IO::Async::Timer" - base class for Notifiers that use timed delays

DESCRIPTION

       This module provides a subclass of IO::Async::Notifier for implementing notifiers that use timed delays. For specific implementations, see
       one of the subclasses:

       o       IO::Async::Timer::Absolute - event callback at a fixed future time

       o       IO::Async::Timer::Countdown - event callback after a fixed delay

       o       IO::Async::Timer::Periodic - event callback at regular intervals

CONSTRUCTOR

   $timer = IO::Async::Timer->new( %args )
       Constructs a particular subclass of "IO::Async::Timer" object, and returns it. This constructor is provided for backward compatibility to
       older code which doesn't use the subclasses. New code should directly construct a subclass instead.

       mode => STRING
	       The type of timer to create. Currently the only allowed mode is "countdown" but more types may be added in the future.

       Once constructed, the "Timer" will need to be added to the "Loop" before it will work. It will also need to be started by the "start"
       method.

METHODS

   $running = $timer->is_running
       Returns true if the Timer has been started, and has not yet expired, or been stopped.

   $timer->start
       Starts the Timer. Throws an error if it was already running.

       If the Timer is not yet in a Loop, the actual start will be deferred until it is added. Once added, it will be running, and will expire at
       the given duration after the time it was added.

       As a convenience, $timer is returned. This may be useful for starting timers at construction time:

	$loop->add( IO::Async::Timer->new( ... )->start );

   $timer->stop
       Stops the Timer if it is running. If it has not yet been added to the "Loop" but there is a start pending, this will cancel it.

NAME

       Xacobeo::Timer - A custom made timer.

SYNOPSIS

	       use Xacobeo::Timer;

	       # As a one time use
	       my $timer = Xacobeo::Timer->start("Long operation");
	       do_long_operation();
	       $timer->elapsed(); # Displays the time elapsed

	       # A simple stop watch (the destructor displays the time elapsed)
	       my $TIMER = Xacobeo::Timer->new("Method calls");
	       sub hotspot {
		       $TIMER->start();
		       # Very slow stuff here
		       $TIMER->stop();
	       }

DESCRIPTION

       This package provides a very simple timer. This timer is used for finding hot spots in the application.

       The timer is quite simple it provides the method "start" that starts the timer and the method "stop" that stops the timer and accumulates
       the elapsed time.  The method "show" can be used to print the time elapsed so far while the method "elapsed" returns the time elapsed so
       far.

       When an instance of this class dies (because it was undefed or collected by the garbage collector) the builtin Perl desctrutor will
       automatically call the method "show". But if the method show or elapsed was called during the lifetime of the instance then the destructor
       will not invoke the method show.

METHODS

       The package defines the following methods:

   new
       Creates a new Timer.

       Parameters:

       o   $name (Optional)

	   The name of the timer.

   start
       Starts the timer. If this sub is called without a blessed instance then a new Timer will be created.

       Parameters:

       o   $name (optional)

	   The name is used only when called without a blessed instance.

   stop
       Stops the timer and adds accumulates the elapsed time. If the timer wasn't started previously this results in a no-op.

   show
       Prints the elapsed time. This method stops the timer if it was started previously and wasn't stopped.

   elapsed
       Returns the total time elapsed so far. If the timer was already started the pending time will not be taking into account.
