Method Detail

run

public void run()

Specified by:

run in interface java.lang.Runnable

getFileFromInputStream

private void getFileFromInputStream()

gets file bytes from input stream and works with it.

serve

public void serve(java.net.Socket socket)
           throws TimeoutException,
                  java.io.IOException,
                  java.security.InvalidParameterException

implementation of method serve from ProtocolHandler

Specified by:

serve in interface FileServer

Parameters:

{@link - java.net.Socket}, the socket that must be served

{@link - java.io.InputStream}, the Stream that must be read from

Throws:

TimeoutException - thrown if connection to the client is lost or too slow.

java.io.IOException - thrown for any I/O error.

java.security.InvalidParameterException - possibly useful

readCommand
