Class IOService

java.lang.Object
  tigase.net.IOService

All Implemented Interfaces:

java.util.concurrent.Callable<IOService>

Direct Known Subclasses:

XMPPIOService

public abstract class IOService
extends java.lang.Object
implements java.util.concurrent.Callable<IOService>

IOService offers thread thread safe call() method execution, however you must be prepared that other methods can be called simultanously like stop(), getProtocol() or isConnected().
It is recomended that developers extend AbsractServerService rather then implement ServerService interface directly.

If you directly implement ServerService interface you must take care about SocketChannel I/O, queueing tasks, processing results and thread safe execution of call() method. If you however extend IOService class all this basic operation are implemented and you have only to take care about parsing data received from network socket. Parsing data is expected to be implemented in parseData(char[] data) method.
