Private method in interface (typescript) is it possible?

Question

typescript

Is it possible to create an interface with a private method:

interface I_Main {
    readonly RUNNING_SPEED: number;

    private getHeight():void;
}

In this case it produces an error: 'private modifier cannot appear on a type member' private getHeight():void;

Answer 1

Interfaces define "Public" properties and methods and have no meaning from an access modifier like protected or privat
You can do something like:

interface IModuleMenuItem {
     getName(): string;
}

class ModuleMenuItem implements IModuleMenuItem {
    private name;

    public getName() {
        return name;    
    }

    protected setName(newName : string) {
        name = newName;
    }
}
