Class SSLSocketConnection

java.lang.Object

com.sshtools.synergy.nio.SocketConnection

com.sshtools.synergy.nio.ssl.SSLSocketConnection

All Implemented Interfaces:

SelectionKeyAware, SelectorRegistrationListener, SocketHandler

public class SSLSocketConnection
extends SocketConnection

This class implements an SSL socket connection for the custom server. Using the Java 1.5 SSLEngine class this implementation wraps all protocol traffic into SSL records.

Constructor and Description
SSLSocketConnection(javax.net.ssl.SSLContext context) Default constructor.
SSLSocketConnection(javax.net.ssl.SSLContext context, boolean allowClientCertificate, boolean requireClientCertificate)

Method Summary

Modifier and Type	Method and Description
boolean	isConnected() Is the socket still connected? During the initial handshake check the raw socket status, otherwise check the protocol status.
boolean	processReadEvent() This method is called when new network data arrives on the socket.
boolean	processWriteEvent() Write any application data to the socket by wrapping it up into the SSL protocol.
void	registrationCompleted(java.nio.channels.SelectableChannel channel, java.nio.channels.SelectionKey key, SelectorThread selectorThread) This method is called once the socket is registered with a SelectorThread.
static void	setEnabledCipherSuites(java.lang.String[] aCipherSuites)
static void	setEnabledProtocols(java.lang.String[] aProtocols)
boolean	wantsWrite() Tell the selector that the handler wants to write.

Constructor Detail

SSLSocketConnection

public SSLSocketConnection(javax.net.ssl.SSLContext context)

Default constructor. We need one of these so we can dynamically create a SocketConnection on demand.

SSLSocketConnection

public SSLSocketConnection(javax.net.ssl.SSLContext context,
                           boolean allowClientCertificate,
                           boolean requireClientCertificate)

Method Detail

registrationCompleted

public void registrationCompleted(java.nio.channels.SelectableChannel channel,
                                  java.nio.channels.SelectionKey key,
                                  SelectorThread selectorThread)

This method is called once the socket is registered with a SelectorThread. At this point we're ready to start transfering data.

Specified by:

registrationCompleted in interface SelectorRegistrationListener

Overrides:

registrationCompleted in class SocketConnection

Parameters:

channel - SelectableChannel

key - SelectionKey

selectorThread - SelectorThread

isConnected

public boolean isConnected()

Is the socket still connected? During the initial handshake check the raw socket status, otherwise check the protocol status.

Overrides:

isConnected in class SocketConnection

Returns:

boolean

processReadEvent

public boolean processReadEvent()

This method is called when new network data arrives on the socket. We have to unwrap any SSL traffic into raw application data

Specified by:

processReadEvent in interface SocketHandler

Overrides:

processReadEvent in class SocketConnection

Parameters:

applicationData - ByteBuffer

Returns:

boolean

processWriteEvent

public boolean processWriteEvent()

Write any application data to the socket by wrapping it up into the SSL protocol.

Specified by:

processWriteEvent in interface SocketHandler

Overrides:

processWriteEvent in class SocketConnection

Parameters:

applicationData - ByteBuffer

Returns:

boolean

wantsWrite

public boolean wantsWrite()

Description copied from interface: SocketHandler

Tell the selector that the handler wants to write.

Specified by:

wantsWrite in interface SocketHandler

Overrides:

wantsWrite in class SocketConnection

Returns:

setEnabledProtocols

public static void setEnabledProtocols(java.lang.String[] aProtocols)

setEnabledCipherSuites

public static void setEnabledCipherSuites(java.lang.String[] aCipherSuites)
