我创建了我的自定义类型,实际上是一个命名的原始类型,目的是为其中的数字或名称类型提供清晰的定义。例如:
export declare type AmountOfCredits = number;
export declare type AmountOfMoney = number;
export declare type AmountOfProduct = number;
export declare type BankAccountNumber = string;
export declare type CompanyName = string;
export declare type CountryName = string;
export declare type DayOfWeek = 0 | 1 | 2 | 3 | 4 | 5 | 6;
export declare type Days = number;
export declare type ID = number;
export declare type Month = number;
// ...etc
现在我可以使用此界面:
export interface EmployeeInterface {
id: ID;
user_id: ID;
mother_name: PersonName;
place_of_birth: SettlementName;
date_of_birth: ISODate;
name: PersonName;
}
但是在课堂上,这也是可行的:
export class Employee implements EmployeeInterface {
id: number;
user_id: number;
mother_name: string;
place_of_birth: string;
date_of_birth: string;
name: string;
}
我可以以某种方式强迫类仅接受自定义声明的类型,而不接受number
或string
基本类型吗?
