DummyTransportResponder

public DummyTransportResponder()

Method Details

getSupportedAddressClass

public Class<? extends Address> getSupportedAddressClass()

Description copied from interface: TransportMapping

Gets the primary 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 actual incoming address this transport mapping uses to listen for incoming packets.

Specified by:

getListenAddress in interface TransportMapping<A extends IpAddress>

Specified by:

getListenAddress in class AbstractTransportMapping<A extends IpAddress>

Returns:

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

sendMessage

public void sendMessage(A address,
 byte[] message,
 TransportStateReference tmStateReference,
 long timeoutMillis,
 int retries)
                 throws IOException

Description copied from class: AbstractTransportMapping

Sends a message to the supplied address using this transport. If the target address has been suspended, then instead actually sending the message on the wire, the method AbstractTransportMapping.handleDroppedMessageToSend(Address, byte[], TransportStateReference, long, int) will be called. To stop suspending of a target address, call AbstractTransportMapping.resumeAddress(Address) for that address.

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.

timeoutMillis - maximum number of milliseconds the connection creation might take (if connection based).

retries - maximum retries during connection creation.

Throws:

IOException - if any underlying IO operation fails.

close

public void close()
           throws IOException

Description copied from interface: TransportMapping

Closes the transport an releases all bound resources synchronously.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface TransportMapping<A extends IpAddress>

Specified by:

close in class AbstractTransportMapping<A extends IpAddress>

Throws:

IOException - if any IO operation for the close fails.

listen

public void listen()
            throws 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, long, int) 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:

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

getListenWorkerTask

public WorkerTask getListenWorkerTask()

Description copied from class: AbstractTransportMapping

Gets the WorkerTask that is responsible for receiving new messages.

Overrides:

getListenWorkerTask in class AbstractTransportMapping<A extends IpAddress>

Returns:

a WorkerTask instance which is most likely a DefaultThreadFactory.WorkerThread.

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.

Specified by:

isListening in interface TransportMapping<A extends IpAddress>

Overrides:

isListening in class AbstractTransportMapping<A extends IpAddress>

Returns:

true if this transport mapping is listening for messages.
