    • Constructor Detail

      • TraceFormat

        public TraceFormat()
        Null constructor for the formatter.
        Parameters:
        None -

        This is the version used when you run TraceFormat from the command line.

      • TraceFormat

        public TraceFormat​(PrintStream outStream,
                   String[] args)
        Constructor used to instantiate the formatter programmatically.
        Parameters:
        args - - the same as you would specify on the command line.

        This version writes to the specified PrintStream.

    • Method Detail

      • main

        public static void main​(String[] args)
        Main entry point for running the formatter.
        Parameters:

      • readAndFormat

        public void readAndFormat​(String[] args,
                          boolean processFully)
        parses command-line args, if in command-line mode, reads the input file(s) and outputs the result
        Parameters:
        args - the command line arguments
        processFully - if true, the formatter will read the trace file and format the tracepoints into a file if false, the formatter will prime the trace file so that an external program can iterate over the tracepoints.
