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