public class SNMPv2TrapPDU

extends SNMPPDU

The SNMPv2TrapPDU class represents an SNMPv2 Trap PDU from RFC 1448, as indicated below. This forms the payload of an SNMPv2 Trap message. -- protocol data units 3.

Fields inherited from class snmp.SNMPSequence

sequence, tag

Constructor Summary

protected	SNMPv2TrapPDU(byte[] enc) Create a new PDU of the specified type from the supplied BER encoding.
	SNMPv2TrapPDU(SNMPObjectIdentifier snmpTrapOID, SNMPTimeTicks sysUptime) Create a new Trap PDU with given trapOID and sysUptime, and containing an empty SNMP sequence (VarBindList) as additional data.
	SNMPv2TrapPDU(SNMPTimeTicks sysUptime, SNMPObjectIdentifier snmpTrapOID, SNMPSequence varList) Create a new Trap PDU with given trapOID and sysUptime, and containing the supplied SNMP sequence as data.

Method Summary

SNMPObjectIdentifier	getSNMPTrapOID() A utility method that extracts the snmpTrapOID from the variable bind list (it's the second of the variable pairs).
SNMPTimeTicks	getSysUptime() A utility method that extracts the sysUptime from the variable bind list (it's the first of the variable pairs).

SNMPv2TrapPDU

public SNMPv2TrapPDU(SNMPObjectIdentifier snmpTrapOID,
                     SNMPTimeTicks sysUptime)
              throws SNMPBadValueException

SNMPv2TrapPDU

protected SNMPv2TrapPDU(byte[] enc)
                 throws SNMPBadValueException

Create a new PDU of the specified type from the supplied BER encoding.

Throws:

SNMPBadValueException - Indicates invalid SNMP PDU encoding supplied in enc.

Method Detail

getSNMPTrapOID

public SNMPObjectIdentifier getSNMPTrapOID()

A utility method that extracts the snmpTrapOID from the variable bind list (it's the second of the variable pairs).

getSysUptime

public SNMPTimeTicks getSysUptime()

A utility method that extracts the sysUptime from the variable bind list (it's the first of the variable pairs).
