bool enableVersioning(bool $enable = true)

Enables/disables versioning of items.

When versioning is enabled, clearing the cache is atomic and doesn't require listing existing keys to proceed, but old keys may need garbage collection and extra round-trips to the back-end are required.

Calling this method also clears the memoized namespace version and thus forces a resynchonization of it.

Parameters

bool $enable

Return Value

bool the previous state of versioning

static protected mixed unserialize(string $value) deprecated
