Class

DrupalCacheArray

Provides a caching wrapper to be used in place of large array structures.

Code

protected function set($data, $lock = TRUE) {
    // Lock cache writes to help avoid stampedes.
    // To implement locking for cache misses, override __construct().
    $lock_name = $this->cid . ':' . $this->bin;
    if (!$lock || lock_acquire($lock_name)) {
        if ($cached = cache_get($this->cid, $this->bin)) {
            $data = $cached->data + $data;
        }
        cache_set($this->cid, $data, $this->bin);
        if ($lock) {
            lock_release($lock_name);
        }
    }
