This is a base class, providing the type-safe static constructor new. This is very convenient when using mixins, as mixins can not have types in the constructors.






  • initialize<T>(props?: Partial<T>): void
  • This method applies its 1st argument (if any) to the current instance using Object.assign().

    Supposed to be overridden in the subclasses to customize the instance creation process.

    Type parameters


    • Optional props: Partial<T>

    Returns void

Static new

  • new<T>(this: T, props?: Partial<InstanceType<T>>): InstanceType<T>
  • This is a type-safe static constructor method, accepting a single argument, with the object, corresponding to the class properties. It will generate a compilation error, if unknown property is provided.

    For example:

    class MyClass extends Base {
        prop     : string
    const instance : MyClass = MyClass.new({ prop : 'prop', wrong : 11 })

    will produce:

    TS2345: Argument of type '{ prop: string; wrong: number; }' is not assignable to parameter of type 'Partial<MyClass>'.
    Object literal may only specify known properties, and 'wrong' does not exist in type 'Partial<MyClass>'

    The only thing this constructor does is create an instance and call the initialize method on it, forwarding the first argument. The customization of instance is supposed to be performed in that method.

    Type parameters


    • this: T
    • Optional props: Partial<InstanceType<T>>

    Returns InstanceType<T>
