Method Detail

acceptback to summary
protected void accept(SocketImpl s)

Overrides java.net.DelegatingSocketImpl.accept.

Doc from java.net.SocketImpl.accept.

Accepts a connection.

Parameters
s:SocketImpl

the accepted connection.

private boolean authenticate(byte method, InputStream in, BufferedOutputStream out, long deadlineMillis) throws IOException
closeback to summary
protected void close() throws IOException

Overrides java.net.DelegatingSocketImpl.close.

Doc from java.net.SocketImpl.close.

Closes this socket.

connectback to summary
protected void connect(String host, int port) throws IOException

Overrides java.net.DelegatingSocketImpl.connect.

Doc from java.net.SocketImpl.connect.

Connects this socket to the specified port on the named host.

Parameters
host:String

the name of the remote host.

port:int

the port number.

if an I/O error occurs when connecting to the remote host.
connectback to summary
protected void connect(InetAddress address, int port) throws IOException

Overrides java.net.DelegatingSocketImpl.connect.

Doc from java.net.SocketImpl.connect.

Connects this socket to the specified port number on the specified host.

Parameters
address:InetAddress

the IP address of the remote host.

port:int

the port number.

Annotations
@Override
Exceptions
IOException:
if an I/O error occurs when attempting a connection.
connectback to summary
protected void connect(SocketAddress endpoint, int timeout) throws IOException

Overrides java.net.DelegatingSocketImpl.connect.

Connects the Socks Socket to the specified endpoint. It will first connect to the SOCKS proxy and negotiate the access. If the proxy grants the connections, then the connect is successful and all further traffic will go to the "real" endpoint.

Parameters
endpoint:SocketAddress

the SocketAddress to connect to.

timeout:int

the timeout value in milliseconds

Annotations
@Override
Exceptions
IOException:
if the connection can't be established.
IllegalArgumentException:
if endpoint is null or a SocketAddress subclass not supported by this socket

protected InetAddress getInetAddress()

Overrides java.net.DelegatingSocketImpl.getInetAddress.

Overrides java.net.DelegatingSocketImpl.listen.

Doc from java.net.SocketImpl.listen.

Sets the maximum queue length for incoming connection indications (a request to connect) to the count argument. If a connection indication arrives when the queue is full, the connection is refused.

Parameters
backlog:int

the maximum length of the queue.
