NAME

       Apache::Singleton - Singleton class for mod_perl

VERSION

       version 0.15

SYNOPSIS

	 package Printer;
	 # default:
	 #   Request for mod_perl env
	 #   Process for non-mod_perl env
	 use base qw(Apache::Singleton);

	 package Printer::PerRequest;
	 use base qw(Apache::Singleton::Request);

	 package Printer::PerProcess;
	 use base qw(Apache::Singleton::Process);

DESCRIPTION

       Apache::Singleton works the same as Class::Singleton, but with various object lifetime (scope). See Class::Singleton first.

OBJECT LIFETIME

       By inheriting one of the following sublasses of Apache::Singleton, you can change the scope of your object.

       Request
	     use base qw(Apache::Singleton::Request);

	   One instance for one request. Apache::Singleton will remove instance on each request. Implemented using mod_perl "pnotes" API. In
	   mod_perl environment (where $ENV{MOD_PERL} is defined), this is the default scope, so inheriting from Apache::Singleton would do the
	   same effect.

	   NOTE: You need "PerlOptions +GlobalRequest" in your apache configuration in order to use the Request lifetime method.

       Process
	     use base qw(Apache::Singleton::Process);

	   One instance for one httpd process. Implemented using package global. In non-mod_perl environment, this is the default scope, and you
	   may notice this is the same beaviour with Class::Singleton ;)

	   So you can use this module safely under non-mod_perl environment.
