Class ProxyConnection

java.lang.Object
  |
  +--ProxyConnection

All Implemented Interfaces:

java.lang.Runnable

public class ProxyConnection

extends java.lang.Object

implements java.lang.Runnable

Represents a connection between a client and a server; a static thread manager manages the number of active and existing threads, and a static ServerSocket waits for connections.

Field Summary

(package private) java.io.InputStream	clientSideIn inputstream from the client
(package private) java.io.OutputStream	clientSideOut outputstream to the client
(package private) java.net.Socket	clientSideSocket the interface with the client
(package private) static ThreadManager	man manages the number of active and existing threads
(package private) boolean	mustCloseConnection to verify if the connection must be closed
(package private) java.io.InputStream	serverSideIn inputstream from the server
(package private) java.io.OutputStream	serverSideOut outputstream to the server
(package private) java.net.Socket	serverSideSocket the interface with the server
(package private) static java.net.ServerSocket	serverSocket all the connection are catched on this ServerSocket

Constructor Summary

(package private)	ProxyConnection() Default constructor, used by the ThreadManager.
(package private)	ProxyConnection(int port) Starts the proxy on the port passed as parameter, or, if already used, on a free port.

Method Summary

(package private) void	launch() Asks the thread manager to create minThreads threads.
void	run() Waits for a connection and manages it until either the client or the server wants close it.
(package private) void	setAttributs(int maxThreads, int minThreads, int maxSpareThreads, int minSpareThreads) Changes the bounds for the number of threads.

Constructor Detail

ProxyConnection

ProxyConnection()

Default constructor, used by the ThreadManager.

ProxyConnection

ProxyConnection(int port)
          throws java.io.IOException

Starts the proxy on the port passed as parameter, or, if already used, on a free port.

Parameters:

port - the TCP port where waiting for connections

Method Detail

setAttributs

void setAttributs(int maxThreads,
                  int minThreads,
                  int maxSpareThreads,
                  int minSpareThreads)
            throws IllegalValuesException

Changes the bounds for the number of threads. It asks the thread manager to do it.

Parameters:

maxThreads - maximum number of existing Threads

minThreads - minimum number of existing Threads

maxSpareThreads - maximum number of disactivated Threads

minSpareThreads - minimum number of disactivated Threads

Throws:

IllegalValuesException -

launch

void launch()
      throws java.io.IOException,
             java.lang.InstantiationException,
             java.lang.IllegalAccessException

Asks the thread manager to create minThreads threads.

Throws:

IOException, - InstantiationException, IllegalValuesException

run

public void run()

Waits for a connection and manages it until either the client or the server wants close it.

Specified by:

run in interface java.lang.Runnable
