setMaxSize method

@override Future<void> setMaxSize(int? maxSize, { EvictionPolicy? evictionPolicy, })

Sets the maximum cache size (applies mainly to in-memory cache).

maxSize - Maximum number of elements. If null, no limit evictionPolicy - Eviction policy when the limit is reached

Implementation

@override
Future<void> setMaxSize(
  int? maxSize, {
  EvictionPolicy? evictionPolicy,
}) async {
  _maxSize = maxSize;

  if (evictionPolicy != null) {
    _evictionPolicy = evictionPolicy;
  }

  // If new max size is smaller than current size, evict entries
  if (_maxSize != null && _cache.length > _maxSize!) {
    final entriesToEvict = _cache.length - _maxSize!;
    for (int i = 0; i < entriesToEvict; i++) {
      _evictOneEntry();
    }
  }
}
