ListRemoveAt

Writer that removes element at index implements IWriter<Element, List>.

IWriterBase<long, List<int>> listRemoveAt;

ListRemoveAt.Create(type) creates implementation for list that implement IList<T>.

IWriterBase<long, List<int>> listRemoveAt =
    (IWriterBase<long, List<int>>)
    ListRemoveAt.Create(typeof(List<int>), typeof(int));

Writer removes an element at index.

// Create list
List<int> list = new List<int> { 1, 2, 3 };
// Remove at index
listRemoveAt.Write(0L, list);

Delegate can be adapted to writer.

IWriter<long, List<int>> listRemoveAt =
    DelegateWriter.Writer((long value, List<int> list) => list.RemoveAt((int)value));

ListRemoveAtRequest is request to create writer.

IRequestFor<IWriterBase> request = new ListRemoveAtRequest(typeof(List<int>));
IWriter<long, List<int>> listRemoveAt = AccessorServices.Instance.GetRequired<IRequest, IWriter<long, List<int>>>(request);

A ref must be used when accessing a value-typed list on stack.

// Create writer
IWriterToRef<long, StructList4<int>> listRemoveAt =
    (IWriterToRef<long, StructList4<int>>)
    ListRemoveAt.Create(typeof(StructList4<int>), typeof(int));
// Create list
StructList4<int> list = new StructList4<int> { 1, 2, 3 };
// Remove at
listRemoveAt.Write(0l, ref list);
// Print "2"
WriteLine(list[0]);

.TypeCast<long, Object>().Write() be used when accessing a value-typed list in heap.

// Create writer
IWriterToRef<long, StructList4<int>> listRemoveAt =
    (IWriterToRef<long, StructList4<int>>)
    ListRemoveAt.Create(typeof(StructList4<int>), typeof(int));
// Create list
StructList4<int> list = new StructList4<int> { 1, 2, 3 };
// Copy to heap
object listBox = list;
// RemoveAt element to the list in heap
listRemoveAt.TypeCast<long, object>().Write(0L, listBox);
// Copy from heap
list = (StructList4<int>)listBox;
// Print "2"
WriteLine(list[0]);
