NAME

MooseX::Types::Moose::Overload - Deal with overload, in the overloaded sense ;)

DESCRIPTION

This module is like MooseX::Types::Moose except it will transparently handle overloaded objects. All you have to do is use it, and then add coerce => 1 to the attributes you wish to enable it on. It will then stringify all objects that support the stringifiy method. This works in the style of overload, forcing Moose to just do you want. Something that stringifies to a string should simply work when the attribute isa Str, right‽ Good, thought so.

This modifies the base types in a slightly ugly way -- I hope to fix this in the future. I reserve the right to remove it from cpan, or change its namespace until it is removed from DEV status; because the base types are global, this attaches to all modules that use the base types. Please see the section on "Future Proofing".

This only attaches a coercion to subtypes of "Value", and it only coerces from "Objects", and only executes on Objects that stringify overload.

SYNOPSIS

        use MooseX::Types::Moose::Overload 'Str';
        use MooseX::Types::Moose::Overload qw/Str Int/;
        use MooseX::Types::Moose::Overload ':all';

        ## Now takes a URI object, or HTTP::Element, and of course a plain string.
        has 'uri' => ( isa => Str, is => 'rw', coerce => 1 );

Future Proofing (TODO)

Currently, this module iterates through all subtypes of "Value" and attaches a coercion with the MooseX::Types1 API. I'm not yet sure if there is a supported method of cloning those base types. Please, do not rely on a naked use MooseX::Types::Moose::Overload; modifying the types exported by MooseX::Types::Moose::Overload. This is an unfortunate side-effect. I really would rather return new fresh types over modify the base types. I didn't realize that the base types were still kinda global.
