formatFileName

protected String formatFileName()

getNextFormatFileName

protected String getNextFormatFileName(String previous)

Method to search forward through dat files. Trace is forward compatible, so a newer JVM should always be able to format the trace from an older JVM. This means that, for example, a 2.3 tracefile can use J9TraceFormat24.dat correctly.

Parameters:

previous - - the last filename tried

Returns:

the next filename to try, or null if all options are exhausted

getServiceLevel

protected String getServiceLevel()

getVMLevel

protected String getVMLevel()
