                        Continuation<SSLSocketManager<Identifier>,Exception> c,
                        boolean server,
                        boolean useClientAuth)

Called on incoming side

Parameters:

transportLayerImpl -

s -

Method Detail

toString

public String toString()

Overrides:

toString in class Object

handleResult

protected void handleResult(SSLEngineResult result)

receiveSelectResult

public void receiveSelectResult(P2PSocket<Identifier> socket,
                                boolean canRead,
                                boolean canWrite)
                         throws IOException

Description copied from interface: P2PSocketReceiver

Called when a socket is available for read/write

Specified by:

receiveSelectResult in interface P2PSocketReceiver<Identifier>

Throws:

IOException

read

protected boolean read()
                throws IOException

Throws:

IOException

handshakeWrap

protected void handshakeWrap()

unwrap

protected void unwrap()
               throws SSLException

Throws:

SSLException

handshakeUnwrap

public X509Certificate getCert()

register

public void register(boolean wantToRead,
                     boolean wantToWrite,
                     P2PSocketReceiver<Identifier> receiver)

Description copied from interface: P2PSocket

Must be called every time a Read/Write occurs to continue operation. Can cancel this task by calling with null.

Specified by:

register in interface P2PSocket<Identifier>

Parameters:

wantToRead - if you want to read from this socket

wantToWrite - if you want to write to this socket

receiver - will have receiveSelectResult() called on it note that you must call select() each time receiveSelectResult() is called. This is so your application can properly handle flow control

Returns:

Throws:

IOException

write

public long write(ByteBuffer srcs)
           throws IOException

Description copied from interface: P2PSocket

Writes a sequence of bytes to this channel from a subsequence of the given buffers.

Specified by:

write in interface P2PSocket<Identifier>

Throws:

IOException

close

public void close()

Description copied from interface: P2PSocket

Closes this socket.

Specified by:

close in interface P2PSocket<Identifier>

getIdentifier

public Identifier getIdentifier()

Description copied from interface: P2PSocket

The identification of the node at the other end of the socket.

Specified by:

getIdentifier in interface P2PSocket<Identifier>

Returns:

a read-only list of options on this socket

shutdownOutput

public void shutdownOutput()

Description copied from interface: P2PSocket

Disables the output stream for this socket. Used to properly close down a socket used for bi-directional communication that can be initated by either side.

Specified by:

shutdownOutput in interface P2PSocket<Identifier>
