Moose::Meta::TypeConstraint::Class - Class/TypeConstraint parallel hierarchy
This class represents type constraints for a class.
Moose::Meta::TypeConstraint::Class is a subclass of
the Moose::Meta::TypeConstraint manpage.
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.
Returns the class name associated with the constraint.
Returns all the type's parent types, corresponding to its parent classes.
is_subtype_of($type_name_or_object) >>
If the given type is also a class type, then this checks that the type's class is a subclass of the other type's class.
Otherwise it falls back to the implementation in the Moose::Meta::TypeConstraint manpage.
create_child_type(%options) >>
This returns a new the Moose::Meta::TypeConstraint manpage object with the type as its parent.
Note that it does not return a
Moose::Meta::TypeConstraint::Class object!
get_message($value) >>
This is the same as get_message in the Moose::Meta::TypeConstraint manpage except
that it explicitly says isa was checked. This is to help users deal
with accidentally autovivified type constraints.
All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT.
