The Law of Demeter or principle of least knowledge is a design guideline for developing software, particularly object-oriented programs. Formally definition, the Law of Demeter requires that a method m of an object O may only invoke the methods of the following kinds of objects: - O itself. - m's parameters. - Any objects created/instantiated within m. - O's direct component objects. - A global variable, accessible by O, in the scope of m. Demeter's law is known as "don't talk to strangers" because: Each unit should have only limited knowledge about other units - only units "closely" related to the current unit. Each unit should only talk to its friends - don't talk to strangers. Only talk to your immediate friends.
