8. SNMP Syntax Classes
Object Modeling Technique
(OMT) view of the SNMP++ SNMP Syntax Classes
The SNMP++ SNMP syntax classes represent an object
oriented C++ view of Structure of Management Information (SMI) Abstract Syntax
Notation (ASN.1) data types which are used by SNMP. Included are a set of
classes which map to the equivalent SMI types. In addition, a few non-SMI classes have
been introduced for ease of use. SNMP++ gives these SNMP data types a powerful,
easy to use interface. Below is a brief description of the various SNMP++
syntax classes.
