Class DummyTransport<A extends IpAddress>

java.lang.Object
  org.snmp4j.transport.AbstractTransportMapping<A>
      org.snmp4j.transport.DummyTransport<A>

All Implemented Interfaces:

TransportMapping<A>

public class DummyTransport<A extends IpAddress>
extends AbstractTransportMapping<A>

The DummyTransport is a test TransportMapping for Command Generators which actually does not sent messages over the network. Instead it provides the message transparently as incoming message over the DummyTransport.DummyTransportResponder on a virtual listen address, regardless to which outbound address the message was sent. The messages are returned even if the listenAddress is left null.

2.0

Method Detail

getSupportedAddressClass

public java.lang.Class<? extends Address> getSupportedAddressClass()

Description copied from interface: TransportMapping

Gets the Address class that is supported by this transport mapping.

Specified by:

getSupportedAddressClass in interface TransportMapping<A extends IpAddress>

Specified by:

getSupportedAddressClass in class AbstractTransportMapping<A extends IpAddress>

Returns:

a subclass of Address.

getListenAddress

public A getListenAddress()

Description copied from interface: TransportMapping

Returns the address that represents the incoming address this transport mapping uses to listen for incoming packets.

Returns:

the address for incoming packets or null this transport mapping is not configured to listen for incoming packets.

setListenAddress

public void setListenAddress(A listenAddress)

sendMessage

public void sendMessage(A address,
                        byte[] message,
                        TransportStateReference tmStateReference)
                 throws java.io.IOException

Description copied from interface: TransportMapping

Sends a message to the supplied address using this transport.

Specified by:

sendMessage in interface TransportMapping<A extends IpAddress>

Specified by:

sendMessage in class AbstractTransportMapping<A extends IpAddress>

Parameters:

address - an Address instance denoting the target address.

message - the whole message as an array of bytes.

tmStateReference - the (optional) transport model state reference as defined by RFC 5590 section 6.1.

Throws:

java.io.IOException - if any underlying IO operation fails.

close

public void close()
           throws java.io.IOException

Description copied from interface: TransportMapping

Closes the transport an releases all bound resources synchronously.

Specified by:

close in interface TransportMapping<A extends IpAddress>

Specified by:

close in class AbstractTransportMapping<A extends IpAddress>

Throws:

java.io.IOException - if any IO operation for the close fails.

listen

public void listen()
            throws java.io.IOException

Description copied from interface: TransportMapping

Listen for incoming messages. For connection oriented transports, this method needs to be called before TransportMapping.sendMessage(A, byte[], org.snmp4j.TransportStateReference) is called for the first time.

Specified by:

listen in interface TransportMapping<A extends IpAddress>

Specified by:

listen in class AbstractTransportMapping<A extends IpAddress>

Throws:

java.io.IOException - if an IO operation exception occurs while starting the listener.

isListening

public boolean isListening()

Description copied from interface: TransportMapping

Returns true if the transport mapping is listening for incoming messages. For connection oriented transport mappings this is a prerequisite to be able to send SNMP messages. For connectionless transport mappings it is a prerequisite to be able to receive responses.

Returns:

true if this transport mapping is listening for messages.

getResponder

public AbstractTransportMapping<A> getResponder(A receiverAddress)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
