3.4.2. Encapsulation. Encapsulation means that the
business logic and implementation are shielded from
the outside world. CBSE supports a variety of
encapsulation types, ranging from white box exposing
all the implementation, or gray box exposing parts of
component implementation to black box. In the cases
of white box and gray box, the component clients have
the flexibility to make modifications to the component
in order to meet specific needs in their solutions.
