ListGet

List getter writer is IWriterToRef<(List, long), Element> writer implementation, where 'long' is the element index.

IWriterToRef<(List<int>, long), int> listGet;

Creating a writer

ListGet<List, Element> is default list writer for IList<T>.

IWriterToRef<(List<int>, long), int> listGet = new ListGet<List<int>, int>();

List.Create(listType, elementType) also creates the writer.

IWriterToRef<(List<int>, long), int> listGet =
    (IWriterToRef<(List<int>, long), int>)
    ListGet.Create(typeof(List<int>), typeof(int));

List get be adapted from delegate.

IWriterToRef<(List<int>, long), int> listGet =
    DelegateWriter.Reader<(List<int>, long), int>(args => args.Item1[(int)args.Item2]);

ListGetRequest(Type) is a request to build a list get writer.

ListGetRequest listRequest = new ListGetRequest(typeof(List<int>));
IWriterToRef<(List<int>, long), int> listGet =
    AccessorServices.Instance
    .GetRequired<ListGetRequest, IWriterToRef<(List<int>, long), int>>(listRequest);

Usage

Writer gets an element at index.

List<int> list = new List<int> { 1, 2, 3 };
int value = listGet.Read((list, 0L));
