| SNMPv1TrapPDU | | public class SNMPv1TrapPDU extends SNMPSequence (Code) | | The SNMPTrapPDU class represents an SNMPv1 Trap PDU from RFC 1157, as indicated below. This
forms the payload of an SNMP Trap message.

| Constructor Summary | |
| public | SNMPv1TrapPDU(SNMPObjectIdentifier enterpriseOID, SNMPIPAddress agentAddress, int genericTrap, int specificTrap, SNMPTimeTicks timestamp, SNMPSequence varList)
Create a new Trap PDU of the specified type, with given request ID, error status, and error index,
and containing the supplied SNMP sequence as data. | | public | SNMPv1TrapPDU(SNMPObjectIdentifier enterpriseOID, SNMPIPAddress agentAddress, int genericTrap, int specificTrap, SNMPTimeTicks timestamp)
Create a new Trap PDU of the specified type, with given request ID, error status, and error index,
and containing an empty SNMP sequence (VarBindList) as additional data. | | protected | SNMPv1TrapPDU(byte[] enc)
Create a new PDU of the specified type from the supplied BER encoding. |
| getAgentAddress | | public SNMPIPAddress getAgentAddress()(Code) | | A utility method that extracts the sending agent address this PDU.
|
| getEnterpriseOID | | public SNMPObjectIdentifier getEnterpriseOID()(Code) | | A utility method that extracts the enterprise OID from this PDU.
|
| getGenericTrap | | public int getGenericTrap()(Code) | | A utility method that returns the generic trap code for this PDU.
|
| getSpecificTrap | | public int getSpecificTrap()(Code) | | A utility method that returns the specific trap code for this PDU.
|
| getTimestamp | | public long getTimestamp()(Code) | | A utility method that returns the timestamp for this PDU.
|
| getVarBindList | | public SNMPSequence getVarBindList()(Code) | | A utility method that extracts the variable binding list from the pdu. Useful for retrieving
the set of (object identifier, value) pairs returned in response to a request to an SNMP
device. The variable binding list is just an SNMP sequence containing the identifier, value pairs.
