| Constructor Summary | |
| public | SNMPPDU(byte pduType, int requestID, int errorStatus, int errorIndex, SNMPSequence varList)
Create a new PDU of the specified type, with given request ID, error status, and error index,
and containing the supplied SNMP sequence as data. | | protected | SNMPPDU(byte[] enc, byte pduType)
Create a new PDU of the specified type from the supplied BER encoding. |
| Method Summary | |
| public int | getErrorIndex()
A utility method that returns the error index for this PDU, identifying the problematic variable. | | public int | getErrorStatus()
A utility method that extracts the error status for this PDU; if nonzero, can get index of
problematic variable using getErrorIndex(). | | public byte | getPDUType()
A utility method that returns the PDU type of this PDU. | | public int | getRequestID()
A utility method that extracts the request ID number from this PDU. | | public SNMPSequence | getVarBindList()
A utility method that extracts the variable binding list from the pdu. |
| SNMPPDU | | public SNMPPDU(byte pduType, int requestID, int errorStatus, int errorIndex, SNMPSequence varList) throws SNMPBadValueException(Code) | | Create a new PDU of the specified type, with given request ID, error status, and error index,
and containing the supplied SNMP sequence as data.
|
| SNMPPDU | | protected SNMPPDU(byte[] enc, byte pduType) throws SNMPBadValueException(Code) | | Create a new PDU of the specified type from the supplied BER encoding.
throws:
SNMPBadValueException - Indicates invalid SNMP PDU encoding supplied in enc. |
| getErrorIndex | | public int getErrorIndex()(Code) | | A utility method that returns the error index for this PDU, identifying the problematic variable.
|
| getErrorStatus | | public int getErrorStatus()(Code) | | A utility method that extracts the error status for this PDU; if nonzero, can get index of
problematic variable using getErrorIndex().
|
| getPDUType | | public byte getPDUType()(Code) | | A utility method that returns the PDU type of this PDU.
|
| getRequestID | | public int getRequestID()(Code) | | A utility method that extracts the request ID number from 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.
