getItem(string $key) : \Psr\Cache\CacheItemInterface

This method must always return a CacheItemInterface object, even in case of a cache miss. It MUST NOT return null.

If the $key string is not a legal value a \Psr\Cache\InvalidArgumentException MUST be thrown.

Arguments

string

The key for which to return the corresponding Cache Item.
