Method Summary

Modifier and Type	Method	Description
protected final void	copySpannedEntryForNextRecord(byte[] buffer, int start, int end)	The end of our Trace Record is copied to the next record
protected int	getNextEntry()	Get the next Trace Entry return 0=no more entries 1=last entry not yet formatted
protected void	prime()	reads in the record data for this TraceRecord
protected final void	spanStart(byte[] startofSpanEntry, int startofSpanEntrySize)	This is called from previous TraceRecord and contains the start of the spanned entry

Methods declared in class TraceRecord

Modifier and Type	Method	Description
final int	compareTo(Object other)	compares this TraceRecord to another based on the time stamp.
protected final String	formatCurrentEntry()	return: the formatted trace entry.
protected final BigInteger	getCurrentTimeStamp()	returns the latest time stamp read so far
protected static final StringBuffer	getIndent(String threadID, boolean doIndent)	sets the indent associated with a given thread id
protected final TraceRecord	getNextRecord()	returns the latest time stamp read so far
protected static final void	initStatics()	Initializes static variables.
protected final int	processNextEntryHeader(byte[] entry, int start)	sets up current* fields for later formatting
