NAME

Specio::Constraint::ObjectDoes - A class for constraints which require an object that does a specific role

VERSION

version 0.24

SYNOPSIS

    my $type = Specio::Constraint::ObjectDoes->new(...);
    print $type->role;

DESCRIPTION

This is a specialized type constraint class for types which require an object that does a specific role.

API

This class provides all of the same methods as Specio::Constraint::Simple, with a few differences:

Specio::Constraint::ObjectDoes->new( ... )

The parent parameter is ignored if it passed, as it is always set to the Defined type.

The inline_generator and constraint parameters are also ignored. This class provides its own default inline generator subroutine reference.

This class overrides the message_generator default if none is provided.

Finally, this class requires an additional parameter, role. This must be a single role name.

$object_isa->role

Returns the role name passed to the constructor.

ROLES

This class does the Specio::Constraint::Role::DoesType, Specio::Constraint::Role::Interface, and Specio::Role::Inlinable roles.
