typescript wrap Array Generic type

Question

I'd like to wrap the generic Array in typescript. We have code as below:

    _bindings: Array<BindingDescription>;

What I want is to have a wrapper around Array so I can use

    _bindings: BindingDescriptionCollection;

I'm trying to wrap it as below:

    export class BindingDescriptionCollection implements Array<BindingDescription> {}

But it need to implements all the functions and properties in Array.

Is there any easier way?

Answer 1

您是要添加其他功能还是仅使用更干净的名称？如果是后者，您可以使用type alias：

type BindingDescriptionCollection = Array<BindingDescription>;

Answer 2

  

但它需要实现Array中的所有函数和属性。   有没有更简单的方法？

您可以使用extend继承功能：

interface BindingDescription{}
class BindingDescriptionCollection extends Array<BindingDescription> {}
