/**
 * Very simple debugger that prints to the console (stdout) the sent and
 * received stanzas. Use this debugger with caution since printing to the
 * console is an expensive operation that may even block the thread since only
 * one thread may print at a time.
 * 

*

* It is possible to not only print the raw sent and received stanzas but also * the interpreted packets by Smack. By default interpreted packets won't be * printed. To enable this feature just change the printInterpreted * static variable to true. * * @author Gaston Dombiak */ public class ConsoleDebugger implements SmackDebugger { public static boolean printInterpreted = false; private SimpleDateFormat dateFormatter = new SimpleDateFormat( "hh:mm:ss aaa"); private Connection connection = null; private PacketListener listener = null; private ConnectionListener connListener = null; private Writer writer; private Reader reader; private ReaderListener readerListener; private WriterListener writerListener; public ConsoleDebugger(Connection connection, Writer writer, Reader reader) { this.connection = connection; this.writer = writer; this.reader = reader; createDebug(); } /** * Creates the listeners that will print in the console when new activity is * detected. */ private void createDebug() { // Create a special Reader that wraps the main Reader and logs data to // the GUI.
