Snippet from the classguidelines of libwy:
...
Not all encapsulated is OOP.
OOP with class is about the complete set of concise and efficient class functionmembers. The point is
about correctness, not only of the codes but more
importantly, of the concept and idea of the class. The idea is not right,
hardly can the class be. If this complete set of class function members is not
doable for no good reasons, such an idea of the class should be abandoned. OOP
in class is not form only, but also semantics...

Not all encapsulated is OOP.
