-// = DESCRIPTION
-// This module contains the class definition for the variable binding (VB)
-// class. The VB class is an encapsulation of a SNMP VB. A VB object is
-// composed of one SNMP++ Oid and one SMI value. The Vb class utilizes Oid
-// objects and thus requires the Oid class. To use this class,
-// set oid, value then call valid() to be sure object was constructed correctly.

-//------------[ VB Class Def ]-------------------------------------
-// The Vb class is the encapsulation of the SNMP variable binding.
-// Variable binding lists in SNMP++ are represented as arrays of
-// Vb objects. Vb objects are passed to and from SNMP objects to
-// provide getting or setting MIB values.
-// The vb class keeps its own memory for objects and does not
-// utilize pointers to external data structures.
-//
