-/**
-* CContext is the implementation class for MNssContext.
-* It encapsulates context data. A context cannot be directly created by a
-* client. A client has to own an instance of Context Manager which has methods
-* for creating context objects. The CContext class also provides additional
-* members for internal use by NssVAS.
