NAME

       Dancer::Timer - a timer for Dancer

SYNOPSIS

	   use Dancer::Timer;

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

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

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

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.

NAME

       Dancer::Object::Singleton - Singleton base class for Dancer

SYNOPSIS

	   package My::Dancer::Extension;

	   use strict;
	   use warnings;
	   use base 'Dancer::Object::Singleton';

	   __PACKAGE__->attributes( qw/name value this that/ );

	   sub init {
	       my ($class, $instance) = @_;
	       # our initialization code, if we need one
	   }

	   # .. later on ..

	   # returns the unique instance
	   my $singleton_intance = My::Dancer::Extension->instance();

DESCRIPTION

       Dancer::Object::Singleton is meantto be used instead of Dancer::Object, if you want your object to be a singleton, that is, a class that
       has only one instance in the application.

       It provides you with attributes and an initializer.

METHODS

   instance
       Returns the instance of the singleton. The instance is created only when needed. The creation will call the "init()" method, which you
       should implement.

   init
       Exists but does nothing. This is so you won't have to write an initializer if you don't want to. init receives the instance as argument.

   get_attributes
       Get the attributes of the specific class.

   attributes
       Generates attributes for whatever object is extending Dancer::Object and saves them in an internal hashref so they can be later fetched
       using "get_attributes".
