Class ThreadLocalPrintStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.Appendable, java.lang.AutoCloseable
    class ThreadLocalPrintStream
extends java.io.PrintStream
    The class name is pretty descriptive. This creates a PrintStream much like a FilterOutputStream, but with the wrapped PrintStream being local to the current Thread. By setting System.out to a ThreadLocalPrintStream, different Threads can write to different PrintStreams simply by using System.out. Of course, the init() method must be called by the Thread that wishes to use the wrapped stream.
