NAME

       Class::MakeMethods::Standard - Make common object accessors

SYNOPSIS

	 package MyObject;
	 use Class::MakeMethods::Standard::Hash (
	   new => 'new',
	   scalar => [ 'foo', 'bar' ],
	   array => 'my_list',
	   hash => 'my_index',
	 );

DESCRIPTION

       This document describes the various subclasses of Class::MakeMethods included under the Standard::* namespace, and the method types each
       one provides.

       The Standard subclasses provide a parameterized set of method-generation implementations.

       Subroutines are generated as closures bound to a hash containing the method name and (optionally) additional parameters.

USAGE AND SYNTAX

       When you "use" a subclass of this package, the method declarations you provide as arguments cause subroutines to be generated and installed
       in your module. You can also omit the arguments to "use" and instead make methods at runtime by passing the declarations to a subsequent
       call to "make()".

       You may include any number of declarations in each call to "use" or "make()". If methods with the same name already exist, earlier calls to
       "use" or "make()" win over later ones, but within each call, later declarations superceed earlier ones.

       You can install methods in a different package by passing "-target_class => package" as your first arguments to "use" or "make".

       See "USAGE" in Class::MakeMethods for more details.

NAME

       Class::MakeMethods::Emulator::Singleton - Emulate Class::Singleton

SYNOPSIS

	 use Class::MakeMethods::Emulator::Singleton;

	 # returns a new instance
	 my $one = Class::MakeMethods::Emulator::Singleton->instance();

	 # returns same instance
	 my $two = Class::MakeMethods::Emulator::Singleton->instance();

COMPATIBILITY

       This module emulates the functionality of Class::Singleton, using Class::MakeMethods to generate similar methods.

       You may use it directly, as shown in the SYNOPSIS above,

       Furthermore, you may call  "use Class::MakeMethods::Emulator::Singleton '-take_namespace';" to alias the Class::Singleton namespace to this
       package, and subsequent calls to the original package will be transparently handled by this emulator. To remove the emulation aliasing,
       call "use Class::MakeMethods::Emulator::Singleton '-release_namespace'".

       Caution: This affects all subsequent uses of Class::Singleton in your program, including those in other modules, and might cause unexpected
       effects.

DESCRIPTION

       A Singleton describes an object class that can have only one instance in any system.  An example of a Singleton might be a print spooler or
       system registry.  This module implements a Singleton class from which other classes can be derived.  By itself, the Class::Singleton module
       does very little other than manage the instantiation of a single object.  In deriving a class from Class::Singleton, your module will
       inherit the Singleton instantiation method and can implement whatever specific functionality is required.

SEE ALSO

       See Class::MakeMethods for general information about this distribution.

       See Class::MakeMethods::Emulator for more about this family of subclasses.

       See Class::Singleton for documentation of the original module.

       For a description and discussion of the Singleton class, see "Design Patterns", Gamma et al, Addison-Wesley, 1995, ISBN 0-201-63361-2.

       See "new" in Class::MakeMethods::Hash and "instance" in Class::MakeMethods::ClassVar for documentation of the created methods.
