ListInsert

Writer that inserts an element to list implements IWriter<(int, Element), List>.

IWriter<(int, long), List<int>> listInsert;

ListInsert.Create(type) creates insert writer for IList<T>.

IWriter<(int, long), List<int>> listInsert = (IWriter<(int, long), List<int>>)ListInsert.Create(typeof(List<int>));

Writer inserts an element to list.

// Create list
List<int> list = new List<int> { 1, 2, 3 };
// Insert element to list
listInsert.WriteAs((100, 1L), list);

Delegate can be adapted to writer.

IWriter<(int, long), List<int>> listInsert =
    (IWriter<(int, long), List<int>>)
    DelegateWriter.Writer(
        ((int value, long index) args, List<int> list) => list.Insert((int)args.index, args.value));

ListInsertRequest is request to query a list-insert-writer from service.

IRequest request = new ListInsertRequest(typeof(List<int>));
IWriter<(int, long), List<int>> listInsert =
    AccessorServices.Instance
    .GetRequired<IRequest, IWriter<(int, long), List<int>>>(request);

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

// Create writer
IWriterToRef<(int, long), StructList4<int>> listInsert =
    (IWriterToRef<(int, long), StructList4<int>>)
    ListInsert.Create(typeof(StructList4<int>));
// Create list
StructList4<int> list = new StructList4<int> { 1, 2, 3 };
// Insert
listInsert.Write((100, 1L), ref list);
// Print
WriteLine(list[1]);

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

// Create writer
IWriterToRef<(int, long), StructList4<int>> listInsert =
    (IWriterToRef<(int, long), StructList4<int>>)
    ListInsert.Create(typeof(StructList4<int>));
// Create list
StructList4<int> list = new StructList4<int> { 1, 2, 3 };
// Copy to heap
object listBox = list;
// Insert element to the list in heap
listInsert.TypeCast<(int, long), object>().Write((100, 1L), listBox);
// Copy from heap
list = (StructList4<int>)listBox;
// Print 
WriteLine(list[1]);
