NAME

       MooseX::MultiMethods - Multi Method Dispatch based on Moose type constraints

VERSION

       version 0.10

SYNOPSIS

	   package Paper;    use Moose;
	   package Scissors; use Moose;
	   package Rock;     use Moose;
	   package Lizard;   use Moose;
	   package Spock;    use Moose;

	   package Game;
	   use Moose;
	   use MooseX::MultiMethods;

	   multi method play (Paper    $x, Rock     $y) { 1 }
	   multi method play (Paper    $x, Spock    $y) { 1 }
	   multi method play (Scissors $x, Paper    $y) { 1 }
	   multi method play (Scissors $x, Lizard   $y) { 1 }
	   multi method play (Rock     $x, Scissors $y) { 1 }
	   multi method play (Rock     $x, Lizard   $y) { 1 }
	   multi method play (Lizard   $x, Paper    $y) { 1 }
	   multi method play (Lizard   $x, Spock    $y) { 1 }
	   multi method play (Spock    $x, Rock     $y) { 1 }
	   multi method play (Spock    $x, Scissors $y) { 1 }
	   multi method play (Any      $x, Any	    $y) { 0 }

	   my $game = Game->new;
	   $game->play(Paper->new, Rock->new);	   # 1, Paper covers Rock
	   $game->play(Spock->new, Paper->new);    # 0, Paper disproves Spock
	   $game->play(Spock->new, Scissors->new); # 1, Spock smashes Scissors

DESCRIPTION

       This module provides multi method dispatch based on Moose type constraints. It does so by providing a "multi" keyword that extends the
       "method" keyword provided by MooseX::Method::Signatures.

       When invoking a method declared as "multi" a matching variant is being searched in all the declared multi variants based on the passed
       parameters and the declared type constraints. If a variant has been found, it will be invoked.  If no variant could be found, an exception
       will be thrown.
