First of all, I'm not sure what Perl's equivalent of Java's bean properties are called (any ideas?). I am using methods of a certain class to store data - eg 
sub entity2 { $_[0]->{entity2}=$_[1] if defined $_[1]; $_[0]->{entity2
+} }
sub IxnCount { $_[0]->{IxnCount}=$_[1] if defined $_[1]; $_[0]->{IxnCo
+unt} }

However the above can only get / set / store scalars. To have object properties which can store arrays, I have been doing the following: 
sub synsatMaxScore1 {    
    my ($self, @pmIDs) = @_; 
    if (@pmIDs) {
        my $ref = \@pmIDs;
        $self->{synsatMaxScore1} = $ref;
    }    
    return $self->{synsatMaxScore1};
}

To set the property, it's  $object->synsatMaxScore1(@array). However it seems that the data can ultimately only be stored as a reference to an array, and also when getting the property, at the moment you then have to derefererence the array: 
my $arrayref = $object->synsatMaxScore1;
my @array = @$arrayref;

Is there any way of changing the method so that it can return arrays too? I guess this is something to do with the way Perl internally handles Object Oriented modules... Thanks in advance.
