ListAdd

Writer that adds elements to list implements interface IWriter<Element, List>.

IWriterBase<int, List<int>> listAdd;

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

IWriter<int, List<int>> listAdd = (IWriter<int, List<int>>)ListAdd.Create(typeof(List<int>));

Writer adds an element to list.

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

Delegate can be adapted to writer.

IWriter<int, List<int>> listAdd = DelegateWriter.Writer((int value, List<int> list) => list.Add(value));

ListAddRequest is request to query a list-add-writer from service.

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

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

// Create writer
IWriterBase<int, StructList4<int>> listAdd = (IWriterBase<int, StructList4<int>>)ListAdd.Create(typeof(StructList4<int>));
// Create list
StructList4<int> list = new StructList4<int> { 1, 2, 3 };
// Add
listAdd.Write(100, ref list);
// Print "100"
WriteLine(list[3]);

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

// Create writer
IWriterBase listAdd = ListAdd.Create(typeof(StructList4<int>));
// Create list
StructList4<int> list = new StructList4<int> { 1, 2, 3 };
// Copy to heap
object listBox = list;
// Add element to the list in heap
listAdd.TypeCast<int, object>().Write(100, listBox);
// Copy from heap
list = (StructList4<int>)listBox;
// Print "100"
WriteLine(list[3]);
