NAME
Moose::Meta::TypeCoercion - The Moose Type Coercion metaclass VERSION
version 2.0604 DESCRIPTION
A type coercion object is basically a mapping of one or more type constraints and the associated coercions subroutines. It's unlikely that you will need to instantiate an object of this class directly, as it's part of the deep internals of Moose. METHODS
Moose::Meta::TypeCoercion->new(%options) Creates a new type coercion object, based on the options provided. o type_constraint This is the Moose::Meta::TypeConstraint object for the type that is being coerced to. $coercion->type_coercion_map This returns the map of type constraints to coercions as an array reference. The values of the array alternate between type names and subroutine references which implement the coercion. The value is an array reference because coercions are tried in the order they are added. $coercion->type_constraint This returns the Moose::Meta::TypeConstraint that was passed to the constructor. $coercion->has_coercion_for_type($type_name) Returns true if the coercion can coerce the named type. $coercion->add_type_coercions( $type_name => $sub, ... ) This method takes a list of type names and subroutine references. If the coercion already has a mapping for a given type, it throws an exception. Coercions are actually $coercion->coerce($value) This method takes a value and applies the first valid coercion it finds. This means that if the value could belong to more than type in the coercion object, the first coercion added is used. Moose::Meta::TypeCoercion->meta This will return a Class::MOP::Class instance for this class. BUGS

NAME
MooseX::Meta::TypeConstraint::ForceCoercion - Force coercion when validating type constraints VERSION
version 0.01 SYNOPSIS
use MooseX::Types:::Moose qw/Str Any/; use Moose::Util::TypeConstraints; use MooseX::Meta::TypeConstraint::ForceCoercion; # get any type constraint my $tc = Str; # declare one or more coercions for it coerce $tc, from Any, via { ... }; # wrap the $tc to force coercion my $coercing_tc = MooseX::Meta::TypeConstraint::ForceCoercion->new( type_constraint => $tc, ); # check a value against new type constraint. this will run the type # coercions for the wrapped type, even if the value already passes # validation before coercion. it will fail if the value couldn't be # coerced $coercing_tc->check('Affe'); DESCRIPTION
This class allows to wrap any "Moose::Meta::TypeConstraint" in a way that will force coercion of the value when checking or validating a value against it. ATTRIBUTES
type_constraint The type constraint to wrap. All methods except for "validate" and "check" are delegated to the value of this attribute. METHODS
check ($value) Same as "Moose::Meta::TypeConstraint::check", except it will always try to coerce $value before checking it against the actual type constraint. If coercing fails the check will fail, too. validate ($value, $coerced_ref?) Same as "Moose::Meta::TypeConstraint::validate", except it will always try to coerce $value before validating it against the actual type constraint. If coercing fails the validation will fail, too. If coercion was successful and a $coerced_ref references was passed, the coerced value will be stored in that. AUTHOR
