Class OutputStreamLogger

java.lang.Object
  oracle.dacf.util.errormanager.ErrorLoggerAdapter
      oracle.dacf.util.errorloggers.OutputStreamLogger

All Implemented Interfaces:

ErrorLogger

public class OutputStreamLogger

extends ErrorLoggerAdapter

The OutPutStreamLogger is a non-buffered logger class that writes error information to an OutputStream. This class extends ErrorLoggerAdapter, which defines an abstract non-buffered logger, and provides implementations of the addError and getName methods.

For example, the following logger code writes to an OutputStream. You can use it to write logging information to any Java Outputstream, for example, a socket, a file, and so on.

   OutputStreamLogger logger = null;
   try
   {
       FileOutputStream fo = new FileOutputStream("tst.out");
       logger = new OutputStreamLogger(fo);
   }
   catch (java.io.IOException e)
   {
        System.err.println("#$%%%$@%@|?!!!!");
   }
   try
   {
        ErrorManager.addErrorLogger(logger);
   }
   catch (NameAlreadyRegisteredException e)
   {
       System.err.println("A Logger with this
                                    name is already registered.");
       return;
   }
  ……………..
   ……………..
   ……………..
   // close the OutputStream, to force flushing
   logger.closeOutputStream();
   ErrorManager.removeErrorLogger(logger);
