=head1 NAME
Specio::Constraint::ObjectDoes - A class for constraints which require an object that does a specific role
=head1 VERSION
version 0.24
=head1 SYNOPSIS
my $type = Specio::Constraint::ObjectDoes->new(...);
print $type->role;
=head1 DESCRIPTION
This is a specialized type constraint class for types which require an object
that does a specific role.
=head1 API
This class provides all of the same methods as L<Specio::Constraint::Simple>,
with a few differences:
=head2 Specio::Constraint::ObjectDoes->new( ... )
The C<parent> parameter is ignored if it passed, as it is always set to the
C<Defined> type.
The C<inline_generator> and C<constraint> parameters are also ignored. This
class provides its own default inline generator subroutine reference.
This class overrides the C<message_generator> default if none is provided.
Finally, this class requires an additional parameter, C<role>. This must be a
single role name.
=head2 $object_isa->role
Returns the role name passed to the constructor.
=head1 ROLES
This class does the L<Specio::Constraint::Role::DoesType>,
L<Specio::Constraint::Role::Interface>, and L<Specio::Role::Inlinable> roles.
