Moose::Meta::TypeConstraint::Role(3) User Contributed Perl DocumentationMoose::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!
