DefaultSshTransportMapping

public DefaultSshTransportMapping(SshTransportAdapter transportAdapter)

Method Details

getSupportedAddressClass

public 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<SshAddress>

Specified by:

getSupportedAddressClass in class AbstractTransportMapping<SshAddress>

Returns:

a subclass of Address.

getListenAddress

public SshAddress getListenAddress()

Description copied from interface: TransportMapping

Returns the address that represents the actual 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.

sendMessage

public void sendMessage(SshAddress address,
 byte[] message,
 TransportStateReference tmStateReference)
                 throws IOException

Description copied from interface: TransportMapping

Sends a message to the supplied address using this transport.

Specified by:

sendMessage in interface TransportMapping<SshAddress>

Specified by:

sendMessage in class AbstractTransportMapping<SshAddress>

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:

IOException - if any underlying IO operation fails.

openSession

protected SshSession openSession(SshAddress address,
 TransportStateReference tmStateReference,
 int maxMessageSize)

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 TransportMapping<SshAddress>

Specified by:

close in class AbstractTransportMapping<SshAddress>

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) is called for the first time.

Specified by:

listen in interface TransportMapping<SshAddress>

Specified by:

listen in class AbstractTransportMapping<SshAddress>

Throws:

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.

fireIncrementCounter

protected void fireIncrementCounter(CounterEvent e)
