getObjectsOverCapacity method
Gets the list of CacheObject that can be removed if the repository is over capacity.
The exact implementation is up to the repository, but implementations should return a preferred list of items. For example, the least recently accessed
Implementation
@override
Future<List<CacheObject>> getObjectsOverCapacity(int capacity) async {
final allSorted = _cacheObjects.values.toList()
..sort((c1, c2) => c1.touched!.compareTo(c2.touched!));
if (allSorted.length <= capacity) return [];
return allSorted.getRange(0, allSorted.length - capacity).toList();
}
