MapReferer

Referer that refers to an bucket of a map implements interface IRefererBase<(Map, Key), Value>.

MapReferer.Create(type) creates implementation for maps that implement Dictionary<Key, Value>.

// Create referer
IReferer<(Dictionary<string, int>, string), int> referer = (IReferer<(Dictionary<string, int>, string), int>)MapReferer.Create(typeof(Dictionary<string, int>));

Referer gets reference to bucket.

// Create map
Dictionary<string, int> map = new Dictionary<string, int> { { "X", 5 }, { "Y", 6 } };
// Get pointer
ref int bucket = ref referer.GetReference((map, "Y"));
// Read
WriteLine(bucket);
// Write
bucket = 100;
// Read
WriteLine(map["Y"]);

MapRefererRequest is request to query a map-element-referer from service.

// Create service
IService service = Services.Create((ServiceHandlers.Instance, AccessorHandlers.Instance), CachePolicies.Default);
// Create request
IRequest request = new MapRefererRequest(typeof(Dictionary<string, int>));
// Create referer
IReferer<(Dictionary<string, int>, string), int> referer = service.GetRequired<IRequest, IReferer<(Dictionary<string, int>, string), int>>(request);
