Simple tuple implementation

This component is simple implementation of immutable ordered sequence of elements with strict types. Which means that once tuple created it can't be immuted. Tuple also provide elements of the same type.

Installation

composer require rocketfellows/tuple

Usage example

Typed item class:

class TupleItem
{
private$id;
publicfunction__construct(int$id)
{
$this->id = $id;
}
publicfunctiongetId(): int
{
return$this->id;
}
}

Items tuple implementation:

userocketfellows\tuple\Tuple;
class Items extends Tuple
{
publicfunction__construct(TupleItem ...$items)
{
parent::__construct(...$items);
}
publicfunctioncurrent(): ?TupleItem
{
returnparent::current();
}
}

Load tuple and loop through:

$firstTupleItem = newTupleItem(1);
$secondTupleItem = newTupleItem(2);
$thirdTupleItem = newTupleItem(3);
$items = newItems($firstTupleItem, $secondTupleItem, $thirdTupleItem);
foreach ($itemsas$item) {
print_r($item->getId());
}

Result:

123
