=head1 NAME
Specio::Constraint::ObjectIsa - A class for constraints which require an object that inherits from a specific class
=head1 VERSION
version 0.12
=head1 SYNOPSIS
my $type = Specio::Constraint::ObjectIsa->new(...);
print $type->class();
=head1 DESCRIPTION
This is a specialized type constraint class for types which require an object
that inherits from a specific class.
=head1 API
This class provides all of the same methods as L<Specio::Constraint::Simple>,
with a few differences:
=head2 Specio::Constraint::ObjectIsa->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<class>. This must be a
single class name.
=head2 $object_isa->class()
Returns the class name passed to the constructor.
=head1 ROLES
This class does the L<Specio::Constraint::Role::IsaType>,
L<Specio::Constraint::Role::Interface>, and L<Specio::Role::Inlinable> roles.
