   * [[Model Principle]] (MP): IH/E demands having an interface for a module which hides the inner workings. MP tells how such an interface can look like.   * [[Model Principle]] (MP): IH/E demands having an interface for a module which hides the inner workings. MP tells how such an interface can look like.
   * [[Liskov Substitution Principle]] (LSP): For subclasses you can waken encapsulation by having a wider ''protected'' interface which can be used by subclasses. For these cases LSP has to be considered, too.   * [[Liskov Substitution Principle]] (LSP): For subclasses you can waken encapsulation by having a wider ''protected'' interface which can be used by subclasses.

   * [[Tell, don't Ask/Information Expert]] (TdA/IE): Encapsulation is about not having getter methods returning constituent internal parts of a module. TdA can be another reason for that.   * [[Tell, don't Ask/Information Expert]] (TdA/IE): Encapsulation is about not having getter methods returning constituent internal parts of a module.
