   Read {@link LoggingEvent} objects sent from a remote client using
   Sockets (TCP). These logging events are logged according to local
   policy, as if they were generated locally.


For example, the socket node might decide to log events to a local file and also resent them to a second socket node. @author Ceki Gülcü @since 0.8.4 */ public class SocketNode implements Runnable { Socket socket; LoggerRepository hierarchy; ObjectInputStream ois; static Logger logger = Logger.getLogger(SocketNode.class); public SocketNode(Socket socket, LoggerRepository hierarchy) { this.socket = socket; this.hierarchy = hierarchy; try { ois = new ObjectInputStream( new BufferedInputStream(socket.getInputStream())); } catch(Exception e) { logger.error("Could not open ObjectInputStream to "+socket, e); } } //public //void finalize() { //System.err.println("-------------------------Finalize called"); // System.err.flush(); //} public void run() { LoggingEvent event; Logger remoteLogger; try { while(true) { // read an event from the wire event = (LoggingEvent) ois.readObject(); // get a logger from the hierarchy. The name of the logger is taken to be the name contained in the event. remoteLogger = hierarchy.getLogger(event.getLoggerName()); //event.logger = remoteLogger; // apply the logger-level filter if(event.getLevel().isGreaterOrEqual(remoteLogger.getEffectiveLevel())) { // finally log the event as if was generated locally remoteLogger.callAppenders(event); } } } catch( e) {"Caught closing conneciton."); } catch( e) {"Caught closing conneciton."); } catch(IOException e) {"Caught "+e);"Closing connection."); } catch(Exception e) { logger.error("Unexpected exception. Closing conneciton.", e); } try { ois.close(); } catch(Exception e) {"Could not close connection.", e); } } }
