      toInt in interface Variable
      Specified by:
      toInt in class AbstractVariable

      public long toLong()
      Description copied from class: AbstractVariable
      Returns a long representation of this variable if such a representation exists.

      Specified by:
      toSubIndex in class AbstractVariable
      Parameters:
      impliedLength - specifies if the sub-index has an implied length. This parameter applies to variable length variables only (e.g. OctetString and OID). For other variables it has no effect.
