All Implemented Interfaces:

Msg, Serializable, SnmpDataType

public class SnmpGauge32

extends SnmpUInt

This class represents 32-bit Snmp Gauge32 type object. The Gauge32 type represents a non-negative integer, which may increase or decrease, but shall never exceed a maximum value. The maximum value can not be greater than 2^32-1 (4294967295 decimal). The value of a Gauge has its maximum value whenever the information being modeled is greater or equal to that maximum value; if the information being modeled subsequently decreases below the maximum value, the Gauge also decreases.
