SYNOPSIS

use Genezzo::Row::RSTab;

# see Tablespace.pm -- implementation and usage is tightly tied

# make a factory for rsfile
my $fac2 = make_fac2('Genezzo::Row::RSFile');

my %args = (
factory => $fac2,
# need tablename, bufcache, etc...
tablename => ...
tso => ...
bufcache => ...
);

my %td_hash;
$tie_val =
tie %td_hash, 'Genezzo::Row::RSTab', %args;

# pushhash style
my @rowarr = ("this is a test", "and this is too");
my $newkey = $tie_val->HPush(@rowarr);

@rowarr = ("update this entry", "and this is too");
$tied_hash{$newkey} = @rowarr;

my $getcount = $tie_val->HCount();
