Properties

The backend options.

public array $options

protected int $weight = 10

public string $namespace

The backends list of capabilities.

private array $capabilities

Standard capabilities are:

store_objects - Backend can directly store & return objects. Whether the backend itself really can (like APCu) or the backend class takes care of this.
compress - Can compress objects being stored. If the backend can do this, then we don't want the frontend to ever do it.
array - Can return all elements in the cache as an associative array
expire_ns - Backend supports storage TTLs on the namespace as a whole.
expire_val - Backend supports storage TTLs on individual values stored within the namespace
keepalive - When a value is accessed it's TTL can be reset to keep it alive in cache.
