Final Class Yiisoft\Cache\NullCache

All Classes | Methods
InheritanceYiisoft\Cache\NullCache
ImplementsPsr\SimpleCache\CacheInterface

NullCache does not cache anything reporting success for all methods calls.

By replacing it with some other cache component, one can quickly switch from non-caching mode to caching mode.

See \Psr\SimpleCache\CacheInterface for common cache operations that NullCache supports.
