Method Detail

accept

public java.net.Socket accept()
                       throws java.io.IOException

Accepts the incoming connection.

Overrides:

accept in class java.net.ServerSocket

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Closes the connection to proxy if socket have not been accepted, if the direct connection is used, closes direct ServerSocket. If the client socket have been allready accepted, does nothing.

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class java.net.ServerSocket

Throws:

java.io.IOException

getHost

public java.lang.String getHost()

Get the name of the host proxy is using to listen for incoming connection.

Usefull when address is returned by proxy as the hostname.

Returns:

the hostname of the address proxy is using to listen for incoming connection.

getInetAddress

public java.net.InetAddress getInetAddress()

Get address assigned by proxy to listen for incomming connections, or the local machine address if doing direct connection.

Overrides:

getInetAddress in class java.net.ServerSocket

getLocalPort

public int getLocalPort()

setSoTimeout

public void setSoTimeout(int timeout)
                  throws java.net.SocketException

Set Timeout.

Overrides:

setSoTimeout in class java.net.ServerSocket

Parameters:

timeout - Amount of time in milliseconds, accept should wait for incoming connection before failing with exception. Zero timeout implies infinity.
