NAME

MooseX::Types::Combine - Combine type libraries for exporting

VERSION

version 0.50

SYNOPSIS

    package CombinedTypeLib;
    use base 'MooseX::Types::Combine';
    __PACKAGE__->provide_types_from(qw/TypeLib1 TypeLib2/);
    package UserClass;
    use CombinedTypeLib qw/Type1 Type2 ... /;

DESCRIPTION

Allows you to create a single class that will allow you to export types from multiple type libraries:

    package TransportTypes;
    use base 'MooseX::Types::Combine';
    __PACKAGE__->provide_types_from(qw/ MotorizedTypes UnmotorizedTypes /);
    1;

In this example all types defined in "MotorizedTypes" and "UnmotorizedTypes" are available through the "TransportTypes" combined type library.

    package SkiingTrip;
    use Moose;
    use TransportTypes qw( CarType SkisType );
    has car => ( is => 'ro', isa => CarType, required => 1 );
    has ski_rack => ( is => 'ro', isa => ArrayRef[SkisType], required => 1 );
    ...

Libraries on the right end of the list passed to "provide_types_from" take precedence over those on the left in case of conflicts. So, in the above example if both the "MotorizedTypes" and "UnmotorizedTypes" libraries provided a "Bike" type, you'd get the bicycle from "UnmotorizedTypes" not the motorbike from "MorotizedTypes".

You can also further combine combined type libraries with additional type libraries or other combined type libraries in the same way to provide even larger type libraries:

    package MeetingTransportTypes;
    use base 'MooseX::Types::Combine';
    __PACKAGE__->provide_types_from(qw/ TransportTypes TelepresenceTypes /);
    1;
