    • DemuxOutputStream

      public DemuxOutputStream​(Project project, boolean isErrorStream)
      Creates a new instance of this class.
      Parameters:
      project - The project instance for which output is being demultiplexed. Must not be null.
      isErrorStream - true if this is the error string, otherwise a normal output stream. This is passed to the project so it knows which stream it is receiving.

    • write

      public void write​(int cc) throws java.io.IOException
      Writes the data to the buffer and flushes the buffer if a line separator is detected or if the buffer has reached its maximum size.
      Specified by:
      write in class java.io.OutputStream
      Parameters:
      cc - data to log (byte).
      Throws:
      java.io.IOException - if the data cannot be written to the stream

    • processBuffer

      protected void processBuffer​(java.io.ByteArrayOutputStream buffer)
      Converts the buffer to a string and sends it to the project.
      Parameters:
      buffer - the ByteArrayOutputStream used to collect the output until a line separator is seen.
      See Also:
      Project.demuxOutput(String,boolean)

    • processFlush

      protected void processFlush​(java.io.ByteArrayOutputStream buffer)
      Converts the buffer to a string and sends it to the project.
      Parameters:
      buffer - the ByteArrayOutputStream used to collect the output until a line separator is seen.
      See Also:
      Project.demuxOutput(String,boolean)

    • close

      public void close() throws java.io.IOException
