## Class IOService<RefObject>

- java.lang.Object
- - tigase.net.IOService<RefObject>

- Type Parameters:
    `RefObject` - is a reference object stored by this service. This is e reference to higher level data object keeping more information about the connection.
  All Implemented Interfaces:
    Callable<IOService<?>>, TLSEventHandler, IOListener
  Direct Known Subclasses:
    XMPPIOService

      public abstract class IOService<RefObject>
      extends Object
      implements Callable<IOService<?>>, TLSEventHandler, IOListener

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

  If you directly implement `ServerService` interface you must take care about `SocketChannel` I/O, queuing 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.
