Tie::FieldVals::Row::Join - a hash tie for merging rows of Tie::FieldVals data

This describes version 0.6202 of Tie::FieldVals::Row::Join.

    use Tie::FieldVals::Row;
    use Tie::FieldVals::Row::Join;

    # just the keys
    my %person_thing;
    my $jr = tie %person_thing, 'Tie::FieldVals::Row::Join,
	fields=>@keys;

    # keys and values
    my %person;
    my $rr = tie %person_thing, 'Tie::FieldVals::Row,
	fields=>@keys;

    my %person_thing;
    my $jr = tie %person_thing, 'Tie::FieldVals::Row::Join,
	row=>$rr;

This is a Tie object to enable the merging of more than one Tie::FieldVals::Row hashes into one hash.

    $row_obj->append_keys(@fields);

Extend the legal fields definition by adding the given fields to it. Sets the given fields to be undefined.

    $row_obj->merge_rows($row_obj2);

Merge a Tie::FieldVals::Row object with this one. The second row object has different Fields than this one, and this will extend the legal fields definition by adding the given fields to it, as well as adding the values of the second row to this row.

Create a new instance of the object as tied to a hash.

    my %person_thing;
    my $jr = tie %person_thing, 'Tie::FieldVals::Row::Join,
	fields=>@keys;

    my %person;
    my $rr = tie %person_thing, 'Tie::FieldVals::Row,
	fields=>@keys;

    my %person_thing;
    my $jr = tie %person_thing, 'Tie::FieldVals::Row::Join,
	row=>$rr;
