Fundamental constants and enumerations.

Some of their values are commonly known, for example the HOURS_COUNT_IN_STELLAR_DAY is 24 and MAXIMAL_DAYS_IN_MONTH is 31. However, without being stored to the constants with clear names, it will be the magic numbers.

Class Integer and Interface IntegerConstructor

The analogue of Number and NumberConstructor respectively pointing that target number is integer. Both class Integer and interface IntegerConstructor are empty. Intended to be used for describing of business rules alongside with native types like String and StringConstructor:

namespace Resident {

  export namespace Age {
    export const TYPE: IntegerConstructor = Integer;
    export const IS_REQUIRED: boolean = true;
    export const MINIMAL_VALUE: number = 0;
    export const MAXIMAL_VALUE: number = 200;
  }

  // Another examle
  export namespace Birthplace {
    export const TYPE: StringConstructor = String;
    export const IS_REQUIRED: boolean = true;
    export const MINIMAL_CHARACTERS_COUNT: number = 1;
    export const MAXIMAL_CHARACETRS_COUNT: number = 255;
  }
  
}
