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.

NAME

       Moose::Meta::TypeConstraint::Enum - Type constraint for enumerated values.

VERSION

       version 2.0604

DESCRIPTION

       This class represents type constraints based on an enumerated list of acceptable values.

INHERITANCE

       "Moose::Meta::TypeConstraint::Enum" is a subclass of Moose::Meta::TypeConstraint.

METHODS

       Moose::Meta::TypeConstraint::Enum->new(%options)
	   This creates a new enum type constraint based on the given %options.

	   It takes the same options as its parent, with several exceptions. First, it requires an additional option, "values". This should be an
	   array reference containing a list of valid string values. Second, it automatically sets the parent to the "Str" type.

	   Finally, it ignores any provided "constraint" option. The constraint is generated automatically based on the provided "values".

       $constraint->values
	   Returns the array reference of acceptable values provided to the constructor.

       $constraint->create_child_type
	   This returns a new Moose::Meta::TypeConstraint object with the type as its parent.

	   Note that it does not return a "Moose::Meta::TypeConstraint::Enum" object!
