WeakMap Adapter (weakMap)

WeakMap Adapter (weakMap)#

Factory: Cache::weakMap(string $namespace = 'default')

Hybrid in-process adapter:

  • scalar/array values stored as encoded blobs

  • object values stored via WeakReference/WeakMap

Object entries remain available while strongly referenced elsewhere. When an object is collected, its cache entry can disappear naturally.

Use when you specifically want object lifecycle-aware caching.

Example#

use Infocyph\CacheLayer\Cache\Cache;

$cache = Cache::weakMap('objects');
$dto = (object) ['id' => 42, 'name' => 'Ada'];

$cache->set('dto:42', $dto, 30);
$sameObject = $cache->get('dto:42');
