我是Spring 4D的新用户。我一直在通过转换一些现有的代码来试验它，我遇到了这个：

{Using System.Generics.Collections}
  TDenonInputList = class(TObjectList<TDenonInput>)
  private
    function GetInputByName(Name: string): TDenonInput;
    function GetInputByRename(Name: string): TDenonInput;
  public
    constructor Create;
    destructor Destroy; override;
    procedure LockedAdd(ADenonInput: TDenonInput);
    procedure LockedClear;
    property Names[Name: string]: TDenonInput read GetInputByName;
    property Renames[Name: string]: TDenonInput read GetInputByRename;
  end;

所以，我通过这样做来转换它：

{Using Spring4D.Collections.Lists}
  IDenonInputList = interface(IList<TDenonInput>)
    ['{2201FB6B-1B9C-4FEE-9614-EFF2A7D35957}']
    function GetInputByName(Name: string): TDenonInput;
    function GetInputByRename(Name: string): TDenonInput;
    procedure LockedAdd(ADenonInput: TDenonInput);
    procedure LockedClear;
    property Names[Name: string]: TDenonInput read GetInputByName;
    property Renames[Name: string]: TDenonInput read GetInputByRename;
  end;

  TDenonInputList = class(TList<TDenonInput>, IDenonInputList)
  private
    function GetInputByName(Name: string): TDenonInput;
    function GetInputByRename(Name: string): TDenonInput;
    procedure LockedAdd(ADenonInput: TDenonInput);
    procedure LockedClear;
  public
    constructor Create;
    destructor Destroy; override;
  end;

然后我通过这样做创建新的列表类型：

var
  InputList: IDenonInputList;
begin
  InputList := TDenonInputList.Create;
   {...}
end;

然而，我读到应该使用TCollections中的工厂函数来创建Spring 4D列表，例如TCollections.CreateList<T>。虽然我所做的工作似乎很好，但我的问题是：有没有更正确的方法来创建IDenonInputList的示例，或者有没有更合适的方法来创建IList的后代并向IList<T>添加额外的函数/属性？
