moose::meta::typeconstraint::role

Moose::Meta::TypeConstraint::Role(3)			User Contributed Perl Documentation		      Moose::Meta::TypeConstraint::Role(3)

NAME

       Moose::Meta::TypeConstraint::Role - Role/TypeConstraint parallel hierarchy

VERSION

       version 2.0604

DESCRIPTION

       This class represents type constraints for a role.

INHERITANCE

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

METHODS

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

	   It takes the same options as its parent, with two exceptions. First, it requires an additional option, "role", which is name of the
	   constraint's role.  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->role
	   Returns the role name associated with the constraint.

       $constraint->parents
	   Returns all the type's parent types, corresponding to the roles that its role does.

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

	   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::Role" object!
