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".

Dancer::Cookies - a singleton storage for all cookies SYNOPSIS
use Dancer::Cookies; my $cookies = Dancer::Cookies->cookies; foreach my $name ( keys %{$cookies} ) { my $cookie = $cookies->{$name}; my $value = $cookie->value; print "$name => $value "; } cookie lang => "fr-FR"; #set a cookie and return its value cookie lang => "fr-FR", expires => "2 hours"; cookie "lang" #return a cookie value DESCRIPTION
Dancer::Cookies keeps all the cookies defined by the application and makes them accessible and provides a few helper functions for cookie handling with regards to the stored cookies. METHODS
init This method is called when "->new()" is called. It creates a storage of cookies parsed from the environment using "parse_cookies_from_env" described below. cookies Returns a hash reference of all cookies, all objects of Dancer::Cookie type. The key is the cookie name, the value is the Dancer::Cookie object. cookie "cookie" method is useful to query or set cookies easily. cookie lang => "fr-FR"; # set a cookie and return its value cookie lang => "fr-FR", expires => "2 hours"; # extra cookie info cookie "lang" # return a cookie value parse_cookie_from_env Fetches all the cookies from the environment, parses them and creates a hashref of all cookies. It also returns all the hashref it created. AUTHOR
