B4J Question jNetwork module - Support multi threading?

[avacondios]

Hi,

Using the jNetwork lib, you can initialise a server UDPSochet, or Serversocket. Calling the Listen method, it starts to listening in the background for incoming connections. Does it support a multithreading on each new incoming connection ? or it is running on the main thread ?

Also, is this an asynchronous ?

Both UDPSocket and ServerSocket listen for connections or packets in the background. If you are using TCP sockets then you should use AsyncStreams to manage the connection. Each connection should use its own AsyncStreams object.

This way multiple connections will not block the main thread.

You can see an example of this in the CCTV example (the one that works with multiple clients).

Hi Erel,

I am asking, because I want to use a map object from main thread (main module) on each new connection event. The map object , will it threadsave on the concurrent connections ? Or each new connection will run on other thread (except from main) and I will have issues ?

In regular apps (non server apps) your code always runs on the main thread.
