    • leftShift

      public GrailsPrintWriter leftShift(Object obj) throws IOException
      Provides Groovy << left shift operator, but intercepts call to make sure nulls are converted to "" strings
      Parameters:
      obj - The value
      Returns:
      Returns this object
      Throws:
      IOException

      Throws:
      IOException

    • checkError

      public boolean checkError()
      Flush the stream if it's not closed and check its error state. Errors are cumulative; once the stream encounters an error, this routine will return true on all successive calls.
      Returns:
      true if the print stream has encountered an error, either on the underlying output stream or during a format conversion.

    • setError

      public void setError()

    • flush

      public void flush()
      Flush the stream.

    • print

      public void print(Object obj)

      Parameters:
      s - The String to be printed

    • write

      public void write(String s)
