NAME

DR::Tarantool::Tuple - tuple container for DR::Tarantool

SYNOPSIS

    my $tuple = new DR::Tarantool::Tuple([ 1, 2, 3]);
    my $tuple = new DR::Tarantool::Tuple([ 1, 2, 3], $space);
    my $tuple = unpack DR::Tarantool::Tuple([ 1, 2, 3], $space);


    $tuple->next( $other_tuple );

    $f = $tuple->raw(0);

    $f = $tuple->name_field;

DESCRIPTION

Tuple contains normalized (unpacked) fields. You can access the fields by their indexes (see raw function) or by their names (if they are described in space).

Each tuple can contain references to next tuple and iterator. So If You extract more than one tuple, You can access them.

METHODS

new

Constructor.

    my $t = DR::Tarantool::Tuple->new([1, 2, 3]);
    my $t = DR::Tarantool::Tuple->new([1, 2, 3], $space);

unpack

Constructor.

    my $t = DR::Tarantool::Tuple->unpack([1, 2, 3], $space);

raw

Returns raw data from tuple.

    my $array = $tuple->raw;

    my $field = $tuple->raw(0);

next

Appends or returns the following tuple.

    my $next_tuple = $tuple->next;

iter

Returns iterator linked with the tuple.

    my $iterator = $tuple->iter;

    my $iterator = $tuple->iter('MyTupleClass', 'new');

    while(my $t = $iterator->next) {
        # the first value of $t and $tuple are the same
        ...
    }

Arguments

package (optional)
method (optional)

if 'package' and 'method' are present, $iterator->next method will construct objects using $package->$method( $next_tuple )

if 'method' is not present and 'package' is present, iterator will bless raw array into 'package'
