=head1 NAME
|
|
|
|
Specio::Constraint::AnyDoes - A class for constraints which require a class name or an object that does a specific role
|
|
|
|
=head1 VERSION
|
|
|
|
version 0.46
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
my $type = Specio::Constraint::AnyDoes->new(...);
|
|
print $type->role;
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This is a specialized type constraint class for types which require a class
|
|
name or 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::AnyDoes->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 $any_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>, L<Specio::Role::Inlinable>, and
|
|
L<MooseX::Clone> roles.
|
