Flow PHP

Wraps another detector and caches its results. On subsequent calls, if the cache file exists, it returns the cached resource instead of running detection again. This is useful for expensive detection operations that don't change during runtime.

The cache is serialized using PHP's serialize/unserialize functions.

Example usage:

// Cache default detectors to system temp directory
$detector = new CachingDetector(
    new ChainDetector(
        new OsDetector(),
        new HostDetector(),
        new ProcessDetector(),
    ),
);

// Cache to custom path
$detector = new CachingDetector(
    new ChainDetector(...$detectors),
    '/var/cache/app/telemetry_resource.cache',
);
