public class PassiveSnmpContextv2c
extends SnmpContextv2c

This class contains the SNMP v2c context that is needed by every Pdu to send a SNMP v2c request in environments where thread creation is unwanted.

This extends SnmpContextv2c so that it does not create any threads to send PDUs. It must be used with the PDU class PassiveTrapPduv2. The original purpose of the Passive classes is to allow the stack to be used in environments where thread creation is unwanted, eg database JVMs such as Oracle JServer. See SNMPv2-PDU.

See notes on how to send traps in an Oracle JServer environment.

Constructor Detail

PassiveSnmpContextv2c

public PassiveSnmpContextv2c(java.lang.String host,
                             int port)
                      throws java.io.IOException

Constructor.

Parameters:

host - The host to which the Pdu will be sent

port - The port where the SNMP server will be

Throws:

java.io.IOException

SnmpContextv2c.SnmpContextv2c(String, int)

PassiveSnmpContextv2c

public PassiveSnmpContextv2c(java.lang.String host,
                             int port,
                             java.lang.String typeSocketA)
                      throws java.io.IOException

Constructor. Parameter typeSocketA should be either STANDARD_SOCKET, TCP_SOCKET or a fully qualified classname.

Parameters:

host - The host to which the Pdu will be sent

port - The port where the SNMP server will be

typeSocketA - The type of socket to use.

Throws:

java.io.IOException

PassiveSnmpContextv2c

protected PassiveSnmpContextv2c(java.lang.String host,
                                int port,
                                java.lang.String bindAddress,
                                java.lang.String typeSocketA)
                         throws java.io.IOException

Constructor. If bindAddress is null, then the system will pick up a valid local address to bind the socket. The typeSocketA will indicate which type of socket to use. This way different handlers can be provided. It should be either STANDARD_SOCKET, TCP_SOCKET or a fully qualified classname.

Parameters:

host - The host to which the Pdu will be sent

port - The port where the SNMP server will be

bindAddress - The local address the server will bind to

typeSocketA - The type of socket to use.

Throws:

java.io.IOException - Thrown when the socket cannot be created.

Method Detail

activate

protected void activate()

Overrides the AbstractSnmpContext.activate() to do nothing. This prevents the creation of threads in the base class.

Overrides:
