ListDefaultConstructor

List default constructor is a writer that creates lists with default values.

IWriterToRef<Avalanche.Void, List<int>> listDefaultConstructor;
IWriterToRef<Avalanche.Void, int[]> arrayDefaultConstructor;

Creating a default constructor

Constructor can be created with a delegate adapter.

var listDefaultConstructor = DelegateWriter.Reader<Avalanche.Void, List<int>>(@void => new List<int>());
var arrayDefaultConstructor = DelegateWriter.Reader<Avalanche.Void, int[]>(@void => Array.Empty<int>());

ListDefaultConstructorRequest(Type) builds a default constructor from list type.

ListDefaultConstructorRequest request = new ListDefaultConstructorRequest(typeof(List<int>));
IWriterToRef<Avalanche.Void, List<int>> myClassDefaultConstructor =
    AccessorServices.Instance
    .GetRequired<ListDefaultConstructorRequest, IWriterToRef<Avalanche.Void, List<int>>>(request);

Usage

Default constructor creates a list from Void.

List<int> myClass = listDefaultConstructor.Read();
int[] myStruct = arrayDefaultConstructor.Read();
