org.snmp4j.smi.OID
The Object Identifier Class. The Object Identifier (OID) class is the encapsulation of an SMI object identifier. The SMI object is a data identifier for a data element found in a Management Information Base (MIB), as defined by a MIB definition. The OID class allows definition and manipulation of object identifiers. @author Frank Fock @version 1.10.1
