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::Class - Class/TypeConstraint parallel hierarchy

VERSION

       version 2.0604

DESCRIPTION

       This class represents type constraints for a class.

INHERITANCE

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

METHODS

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

	   It takes the same options as its parent, with two exceptions. First, it requires an additional option, "class", which is name of the
	   constraint's class.	Second, it automatically sets the parent to the "Object" type.

	   The constructor also overrides the hand optimized type constraint with one it creates internally.

       $constraint->class
	   Returns the class name associated with the constraint.

       $constraint->parents
	   Returns all the type's parent types, corresponding to its parent classes.

       $constraint->is_subtype_of($type_name_or_object)
	   If the given type is also a class type, then this checks that the type's class is a subclass of the other type's class.

	   Otherwise it falls back to the implementation in Moose::Meta::TypeConstraint.

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

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

       $constraint->get_message($value)
	   This is the same as "get_message" in Moose::Meta::TypeConstraint except that it explicitly says "isa" was checked. This is to help
	   users deal with accidentally autovivified type constraints.
