Class NullOutputStream

java.lang.Object
  java.io.OutputStream
      org.xerial.util.io.NullOutputStream

All Implemented Interfaces:

public class NullOutputStream
extends OutputStream

The usage of NullOutputStream is to switch on/off of message outputs without modifying or commenting out println(...) methods. For example,

        
 PrintStream log = new PrintStream(System.out); // output messages to be displayed to std. out
 // PrintStream log = new PrintStream(new NullOutputStream());  // no output will be generated
 
 log.println("some messages");
