=head1 NAME
Specio::Constraint::ObjectCan - A class for constraints which require an object with a set of methods
=head1 VERSION
version 0.33
=head1 SYNOPSIS
my $type = Specio::Constraint::ObjectCan->new(...);
print $_, "\n" for @{ $type->methods };
=head1 DESCRIPTION
This is a specialized type constraint class for types which require an object
with a defined set of methods.
=head1 API
This class provides all of the same methods as L<Specio::Constraint::Simple>,
with a few differences:
=head2 Specio::Constraint::ObjectCan->new( ... )
The C<parent> parameter is ignored if it passed, as it is always set to the
C<Object> 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<methods>. This must be
an array reference of method names which the constraint requires. You can also
pass a single string and it will be converted to an array reference
internally.
=head2 $object_can->methods
Returns an array reference containing the methods this constraint requires.
=head1 ROLES
This class does the L<Specio::Constraint::Role::CanType>,
L<Specio::Constraint::Role::Interface>, and L<Specio::Role::Inlinable> roles.
