Dans les définitions de types d'une bibliothèque Node.js standard, j'ai trouvé une définition de l'interface DateConstructor
.Signature d'interface TypeScript "(): chaîne"
interface DateConstructor {
new(): Date;
new(value: number): Date;
new(value: string): Date;
new(year: number, month: number, date?: number, hours?: number, minutes?: number, seconds?: number, ms?: number): Date;
(): string;
readonly prototype: Date;
/**
* Parses a string containing a date, and returns the number of milliseconds between that date and midnight, January 1, 1970.
* @param s A date string
*/
parse(s: string): number;
/**
* Returns the number of milliseconds between midnight, January 1, 1970 Universal Coordinated Time (UTC) (or GMT) and the specified date.
* @param year The full year designation is required for cross-century date accuracy. If year is between 0 and 99 is used, then year is assumed to be 1900 + year.
* @param month The month as an number between 0 and 11 (January to December).
* @param date The date as an number between 1 and 31.
* @param hours Must be supplied if minutes is supplied. An number from 0 to 23 (midnight to 11pm) that specifies the hour.
* @param minutes Must be supplied if seconds is supplied. An number from 0 to 59 that specifies the minutes.
* @param seconds Must be supplied if milliseconds is supplied. An number from 0 to 59 that specifies the seconds.
* @param ms An number from 0 to 999 that specifies the milliseconds.
*/
UTC(year: number, month: number, date?: number, hours?: number, minutes?: number, seconds?: number, ms?: number): number;
now(): number;
}
declare const Date: DateConstructor;
Il contient la définition étrange (): string
. Comment puis-je le définir en classe, qui veut implémenter cette interface?
