  • Method Details

    • intialize

      public static PrintStream[] intialize()
      Starts the redirection of System.out and System.err.
      Returns:
      Array of length 2 original output streams, index 0 = stdout, 1 = stderr.
      Throws:
      IllegalStateException - If this has already been done.
      SecurityException - If a security manager exists and its checkPermission method doesn't allow reassigning of the standard output or error output stream.

    • getRealStdErr

      public static PrintStream getRealStdErr()
      Gets the real System.err from before it was redirected from the system, i.e. the stream that bypasses the redirection into the loggers.

      The saved stream is answered only while this class' own redirecting stream is the one currently installed as System.err. If the redirection was never started, has been shut down, or someone else has replaced System.err since, there is no redirection of ours left to bypass: null is answered so the caller writes to the current System.err rather than to a stale stream captured once, process wide, at class initialization.

      Returns:
      The real System.err, or null when this class is not the redirection currently installed as System.err.
