Views in Object-Oriented Programming

COB(C with OBjects) is an object-oriented extension of C developed at IBM Research, Tokyo Research Laboratory. Main emphasis of COB is on program organization, compile-time type checking, reusability, and good run-time performance. COB uses classes as the primary means or organization and as the basic unit of object-oriented programming. One of the unique features COB introduces is the notion of class views. The programmer can use views to control the visibility of class information and an appropriate balance between run-time performance and the need for recompilation. This paper explains the notion of class views of COB in detail.
