DR::Tarantool::Tuple - tuple container for DR::Tarantool
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;
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.
Constructor.
my $t = DR::Tarantool::Tuple->new([1, 2, 3]); my $t = DR::Tarantool::Tuple->new([1, 2, 3], $space);
my $t = DR::Tarantool::Tuple->unpack([1, 2, 3], $space);
Returns raw data from tuple.
my $array = $tuple->raw; my $field = $tuple->raw(0);
Appends or returns the following tuple.
my $next_tuple = $tuple->next;
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 ... }
if 'package' and 'method' are present, $iterator->next method will construct objects using $package->$method( $next_tuple )
$package->$method( $next_tuple )
if 'method' is not present and 'package' is present, iterator will bless raw array into 'package'
Returns tail of tuple (array of unnamed fields). The function always return ARRAYREF (as raw).
