Implementation

@override
bool tryGetValue<T>(Object key, void Function(T? value) setValue) {
  final entry = _entries[key];

  if (entry == null) {
    if (_options.trackStatistics) {
      _missCount++;
    }
    setValue(null);
    return false;
  }

  // Check if expired
  if (entry.isExpired) {
    removeEntry(key, EvictionReason.expired);
    if (_options.trackStatistics) {
      _missCount++;
    }
    setValue(null);
    return false;
  }

  // Update last accessed for sliding expiration
  entry.updateLastAccessed();

  if (_options.trackStatistics) {
    _hitCount++;
  }

  setValue(entry.value as T?);
  return true;
}
