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
A 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 the space).Each tuple can contain references to next tuple and iterator, so that if the server returns more than one tuple, all of them can be accessed.
METHODS
new
A constructor.
my $t = DR::Tarantool::Tuple->new([1, 2, 3]);
my $t = DR::Tarantool::Tuple->new([1, 2, 3], $space);
unpack
Another way to construct a tuple.
my $t = DR::Tarantool::Tuple->unpack([1, 2, 3], $space);
raw
Return raw data from the tuple.
my $array = $tuple->raw;
my $field = $tuple->raw(0);
next
Append or return the next tuple, provided there is more than one tuple in the result set.
my $next_tuple = $tuple->next;
iter
Return an iterator object associated 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, $iterator->next method
constructs objects using "$package->$method( $next_tuple )"
If 'method' is not present and 'package' is present, the iterator blesses the raw array with 'package'.
tail
Return the tail of the tuple (array of unnamed fields). The function always returns ARRAYREF (as raw).COPYRIGHT AND LICENSE
