All Implemented Interfaces:

java.lang.Cloneable, java.util.EventListener, java.lang.Runnable, SnmpContextBasisFace, SnmpContextFace, SnmpContextv2cFace, TrapListener

Direct Known Subclasses:

PassiveSnmpContextv2c

public class SnmpContextv2c

extends SnmpContext

implements SnmpContextv2cFace, java.lang.Cloneable

This class contains the SNMP v2c context that is needed by every Pdu to send a SNMP v2c request.

destroy() should be called when the context is no longer used. This is the only way the threads will be stopped and garbage collected.

Method Detail

getVersion

public int getVersion()

Description copied from interface: SnmpContextBasisFace

Return the SNMP version of the context.

Specified by:

getVersion in interface SnmpContextBasisFace

Overrides:

getVersion in class SnmpContext

Following copied from interface: uk.co.westhawk.snmp.stack.SnmpContextBasisFace

Returns:

The version

encodePacket

public byte[] encodePacket(byte msg_type,
                           int rId,
                           int errstat,
                           int errind,
                           java.util.Enumeration ve)

encodePacket in interface SnmpContextBasisFace

Overrides:

encodePacket in class SnmpContext

Following copied from interface: uk.co.westhawk.snmp.stack.SnmpContextBasisFace

Returns:

The encoded packet

ProcessIncomingMessage

protected void ProcessIncomingMessage(uk.co.westhawk.snmp.stack.AsnDecoder rpdu,
                                      java.io.ByteArrayInputStream in)
                               throws DecodingException,
                                      java.io.IOException

Processes an incoming SNMP v2c message.

Overrides:

ProcessIncomingMessage in class SnmpContext

Following copied from class: uk.co.westhawk.snmp.stack.AbstractSnmpContext

See Also:

AbstractSnmpContext.run()
