NAME

       Class::MakeMethods::Template::Ref - Universal copy and compare methods

SYNOPSIS

	 package MyObject;
	 use Class::MakeMethods::Template::Ref (
	   'Hash:new'	   => [ 'new' ],
	   clone	   => [ 'clone' ]
	 );

	 package main;

	 my $obj = MyObject->new( foo => ["Foozle", "Bozzle"] );
	 my $clone = $obj->clone();
	 print $obj->{'foo'}[1];

DESCRIPTION

       The following types of methods are provided via the Class::MakeMethods interface:

   clone
       Produce a deep copy of an instance of almost any underlying datatype.

       Parameters:

       init_method

       If defined, this method is called on the new object with any arguments passed in.

   prototype
       Create new instances by making a deep copy of a static prototypical instance.

       Parameters:

       init_method

       If defined, this method is called on the new object with any arguments passed in.

   compare
       Compare one object to another.

       Templates

       o   default

	   Three-way (sorting-style) comparison.

       o   equals

	   Are these two objects equivalent?

       o   identity

	   Are these two references to the exact same object?

NAME

       Class::MakeMethods::Emulator::accessors - Emulate the accessors module

SYNOPSIS

	 package Foo;
	 use Class::MakeMethods::Emulator::accessors qw( foo bar baz );

	 my $obj = bless {}, 'Foo';

	 # generates chaining accessors:
	 $obj->foo( 'hello ' )
	     ->bar( 'world' )
	     ->baz( "!
" );

	 print $obj->foo, $obj->bar, $obj->baz;

       This module also defines subpackages for the classic and chaining subclasses:

	 package Bar;
	 use Class::MakeMethods::Emulator::accessors;
	 use Class::MakeMethods::Emulator::accessors::classic qw( foo bar baz );

	 my $obj = bless {}, 'Bar';

	 # always return the current value, even on set:
	 $obj->foo( 'hello ' ) if $obj->bar( 'world' );

	 print $obj->foo, $obj->bar, $obj->baz( "!
" );

DESCRIPTION

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

       In particular, the following lines are equivalent:

	 use accessors 'foo';
	 use Class::MakeMethods::Template::Hash 'scalar --get_set_chain' => 'foo';

	 use accessors::chained 'foo';
	 use Class::MakeMethods::Template::Hash 'scalar --get_set_chain' => 'foo';

	 use accessors::classic 'foo';
	 use Class::MakeMethods::Template::Hash 'scalar' => 'foo';

       You may use this module directly, as shown in the SYNOPSIS above,

       Furthermore, you may call "use Class::MakeMethods::Emulator::accessors '-take_namespace';" to alias the accessors 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::accessors '-release_namespace'".  The same mechanism is also available for the classic and chained
       subclasses.

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