1 cache.inc cache($bin = 'cache')

Instantiates and statically caches the correct class for a cache bin.

By default, this returns an instance of the BackdropDatabaseCache class. Classes implementing BackdropCacheInterface can register themselves both as a default implementation and for specific bins.


$bin: The cache bin for which the cache object should be returned, defaults to 'cache'.

Return value

BackdropCacheInterface: The cache object associated with the specified bin.
