VersionStringGenerator::cache_entry_exists
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.
Method of the class: VersionStringGenerator{}
No Hooks.
Returns
bool. True if an entry appears to be stored, false if this looks like a miss.
Usage
// private - for code of main (parent) class only $result = $this->cache_entry_exists( $value, $found ): bool;
- $value(mixed) (required)
- The value returned by wp_cache_get().
- $found(mixed) (required)
- The found flag as populated by wp_cache_get(), if it populates it at all.
