Class SaslSocketTransceiver

java.lang.Object
  org.apache.avro.ipc.Transceiver
      org.apache.avro.ipc.SaslSocketTransceiver

All Implemented Interfaces:

Closeable

public class SaslSocketTransceiver
extends Transceiver

A Transceiver that uses javax.security.sasl for authentication and encryption.

Constructor Summary

SaslSocketTransceiver(SocketAddress address)
Create using SASL's anonymous (RFC 2245) mechanism.

SaslSocketTransceiver(SocketAddress address, SaslClient saslClient)
Create using the specified SaslClient.

SaslSocketTransceiver(SocketChannel channel, SaslServer saslServer)
Create using the specified SaslServer.

Method Summary

void	close()
Protocol	getRemote() Returns the protocol passed to Transceiver.setRemote(Protocol).
String	getRemoteName()
boolean	isConnected() True if a handshake has been completed for this connection.
List<ByteBuffer>	readBuffers() Called by the default definition of Transceiver.transceive(List).
void	setRemote(Protocol remote) Called with the remote protocol when a handshake has been completed.
List<ByteBuffer>	transceive(List<ByteBuffer> request) Called by Requestor.request(String,Object) for two-way messages.
void	writeBuffers(List<ByteBuffer> buffers) Called by Requestor.request(String,Object) for one-way messages.

Method Detail

isConnected

public boolean isConnected()

Description copied from class: Transceiver

True if a handshake has been completed for this connection. Used to determine whether a handshake need be completed prior to a one-way message. Requests and responses are always prefixed by handshakes, but one-way messages. If the first request sent over a connection is one-way, then a handshake-only response is returned. Subsequent one-way messages over the connection will have no response data sent. Returns false by default.

Overrides:

isConnected in class Transceiver

setRemote

public void setRemote(Protocol remote)

Description copied from class: Transceiver

Called with the remote protocol when a handshake has been completed. After this has been called and while a connection is maintained, Transceiver.isConnected() should return true and #getRemote() should return this protocol. Does nothing by default.

Overrides:

setRemote in class Transceiver

getRemote

public Protocol getRemote()

Description copied from class: Transceiver

Returns the protocol passed to Transceiver.setRemote(Protocol). Throws IllegalStateException by default.

Overrides:

getRemote in class Transceiver

getRemoteName

public String getRemoteName()

Specified by:

getRemoteName in class Transceiver

transceive

public List<ByteBuffer> transceive(List<ByteBuffer> request)
                            throws IOException

Description copied from class: Transceiver

Called by Requestor.request(String,Object) for two-way messages. By default calls Transceiver.writeBuffers(List) followed by Transceiver.readBuffers().

Overrides:

transceive in class Transceiver

Throws:

IOException

readBuffers

public List<ByteBuffer> readBuffers()
                             throws IOException

Description copied from class: Transceiver

Called by the default definition of Transceiver.transceive(List).

Specified by:

readBuffers in class Transceiver

Throws:

IOException

writeBuffers

public void writeBuffers(List<ByteBuffer> buffers)
                  throws IOException

Description copied from class: Transceiver

Called by Requestor.request(String,Object) for one-way messages.

Specified by:

writeBuffers in class Transceiver

Throws:

IOException

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Overrides:

close in class Transceiver

Throws:

IOException
