Constructor Details

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 Details

main

public static void main(String[] args)

Main entry point for running the formatter.

Parameters:

args -

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.
