VersionStringGenerator::cache_entry_exists │ private │ WC 1.0

Tell whether a value read from the cache is evidence that an entry is stored.

Object cache drop-ins replace wp_cache_get() wholesale, so neither the returned value nor the found flag is trustworthy on its own: some drop-ins never populate $found, and some signal a miss with null rather than false. The value is therefore the primary evidence, with $found as a tie-breaker that tells a stored false apart from a genuine miss. $found is checked loosely because a drop-in may report it as a truthy non-boolean.

bool. True if an entry appears to be stored, false if this looks like a miss.
