C# Hazelcast IIIdentifiedDataSerializable对象嵌套集合

我是Hazelcast的新手，正在尝试理解如何正确序列化和反序列化嵌套的对象集合

假设我有一个类似的类，但我正在实现

IIdentifiedDataSerializable

class Customer : IIdentifiedDataSerializable
{
    int Id { get; set; }
    List<Address> Addresses  { get; set; }
    CustomerDetails Details  { get; set; }
}

// this works fine
output.WriteObject(Addresses);

// successfully get my collection back
Addresses = input.ReadObject<List<Address>>();

public void ReadData(IObjectDataInput input)
{
    Id = input.ReadInt();

    // pseudo code works, but how do I know when to move on?
    loop
    {
        var addr = new Address();
        addr.ReadData(input);
        Addresses.Add(addr);
    }

    var detail = new CustomerDetails();
    detail.ReadData(input);
    Details = detail;
}
