Map implements ArrayAccess, Countable, Iterator

FinalYes

Map implementation that supports objects as keys.

PHP's \WeakMap is not an option in case object keys are created and assigned in an encapsulated scope (like passing a map to a function to enrich it). In case the original object is not referenced anymore, it also will vanish from a \WeakMap, when used as key (see https://www.php.net/manual/class.weakmap.php).

PHP's \SplObjectStorage has a strange behavior when using an iteration like foreach ($map as $key => $value) - the $value is actually the $key for BC reasons (see https://bugs.php.net/bug.php?id=49967).

This individual implementation works around the "weak" behavior of \WeakMap and the iteration issue with foreach of \SplObjectStorage by acting as a wrapper for \SplObjectStorage with reduced features.

Example:

$map = new \TYPO3\CMS\Core\Type\Map();
$key = new \stdClass();
$value = new \stdClass();
$map[$key] = $value;

foreach ($map as $key => $value) { ... }
