Simple Echo Protocol

A simple protocol component that echoes back anything sent to it.

It simply copies its input to its output.

Example Usage

A simple server that accepts connections on port 1501, echoing back anything sent to it:

>>> SimpleServer(protocol=EchoProtocol, port=1501).run()

On a unix/linux client:

> telnet <server ip> 1501
Trying <server ip>...
Connected to <server ip>...
hello world, this will be echoed back when I press return (newline)
hello world, this will be echoed back when I press return (newline)
oooh, thats nice!
oooh, thats nice!

How does it work?

The component receives data on its "inbox" inbox and immediately copies it to its "outbox" outbox.

If a producerFinished or shutdownMicroprocess message is received on its "control" inbox, the component sends a producerFinished message to its "signal" outbox and terminates.
