DR::Tarantool::Tuple(3pm) User Contributed Perl Documentation DR::Tarantool::Tuple(3pm)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, default: new)
if 'package' and 'method' are present, $iterator->next method will construct objects using "$package->$method( $next_tuple )"
AUTOLOAD
Each tuple autoloads fields by their names that defined in space.
my $name = $tuple->password; # space contains field with name 'password'
my $name = $tuple->login;
...
tuple iterators
new
my $iter = DR::Tarantool::Tuple::Iterator->new( $tuple );
my $iter = $tuple->iter; # the same
Arguments
tuple
package (optional)
method (optional, default: new)
if 'package' and 'method' are present, next method will construct objects using "$package->$method( $next_tuple )"
count
Returns count of tuples in the iterator.
my $count = $iter->count;
reset
Resets iterator (see next method).
$iter->reset;
next
Returns next element from the iterator.
my $iter = $tuple->iter;
while(my $tuple = $iter->next) {
...
}
