[Sqlrelay-discussion] SQLRelay perl API - sub-classing SQLRelay::Cursor

[Victor <vi...@vs...>]

Hello!

I have a problem with perl SQLRelay API.

I want to sub-class SQLRelay classes to add few methods for myself.

like

package MySQLRelayCursor;

use base SQLRelay::Cursor;

i want to add few fields as well

sub new {
        my ($class, $con)=@_;
        return undef unless defined $con;
        my $self=SQLRelay::Cursor->new($con);
        $self->getNullsAsUndefined(); # it is a real mess when you see mysql nulls as empty strings
        $self->{MyField1} = 1; # new field!
        $self->{MyField2} = 2; # new field!
        bless $self, $class;
        return $self;
}

and i am getting error
Not a HASH reference at /path/to/file ...

I think this means that you have no line like
my $self = {}; # ref to empty hash 
in SQLRelay::Cursor::new or XS analog

Am I wrong ?
Maybe i just have some error in connections and in normal situation it returns hash ref ?
What is the best way to inherit SQLRelay::Cursor ? Maybe better make it aggregated object ?
What is the best practice for this ?
