java.lang.Object

at.borkowski.spicej.proxy.SocketProxy

All Implemented Interfaces:

Runnable

public class SocketProxy
extends Object
implements Runnable

A proxy provider for TCP connections allowing for upstream and downstream rate limitation. This proxy listens for connections on a local port and forwards data to and from a connection to a remote port upon local connection. Upstream and downstream rate limitations are possible.

Constructor Detail

SocketProxy

public SocketProxy(int localPort,
                   String remoteHost,
                   int remotePort,
                   Float rateUp,
                   Float rateDown,
                   Float delayUp,
                   Float delayDown)

Creates a proxy and binds to the local port.

Parameters:

localPort - the local port to listen on

remoteHost - the remote host to connect to

remotePort - the remote port to connect to

rateUp - the upstream rate limitation to establish, or null for no limit

rateDown - the downstream rate limitation to establish, or null for no limit

delayUp - the delay to add to the uplink stream, or null for no delay

delayDown - the delay to add to the downlink stream, or null for no delay

Method Detail

initialize

public void initialize()
                throws IOException

Initializes the proxy provider. This method must be called before the actual use and is required for testability reasons.

Throws:

IOException - If the initialization fails.

run

public void run()

Specified by:
