Passthrough of data
The PassThrough component simply passes through data from its "inbox" inbox to its "outbox" outbox.
This can be used, for example, as a dummy 'protocol' component - slotting it into a system where ordinarily a component would go that somehow changes or processes the data passing through it.
Creating a simple tcp socket server on port 1850 that echoes back to clients whatever they send to it:
def echoProtocol: return PassThrough() SimpleServer( protocol=echoProtocol, port=1850 ).run()
Send any item to PassThrough component's "inbox" inbox and it will immediately be sent on out of the "outbox" outbox.
If a producerFinished or shutdownMicroprocess message is received on the "control" inbox then this component will immediately terminate. It will send the message on out of its "signal" outbox. Any pending data waiting in the "inbox" inbox may be lost.
Got a problem with the documentation? Something unclear that could be clearer? Want to help improve it? Constructive criticism is very welcome - especially if you can suggest a better rewording!
Please leave you feedback here in reply to the documentation thread in the Kamaelia blog.
