void edu.rice.cs.hpc.traceviewer.db.remote.DecompressionThread.decompress ( DecompressionItemToDo toDecomp ) throws IOException [private]

Definition at line 140 of file DecompressionThread.java.

DataRecord [] edu.rice.cs.hpc.traceviewer.db.remote.DecompressionThread.readTimeCPIDArray	(	byte[]	packedTraceLine,
		int	length,
		long	t0,
		long	tn,
		int	compressed
	)			throws IOException `[private]`

Reads from the stream and creates an array of Timestamp-CPID pairs containing the data for this rank.

Parameters:

	packedTraceLine
	length	The number of Timestamp-CPID pairs in this rank (not the length in bytes)
	t0	The start time
	tn	The end time
	compressed

Exceptions:

IOException

void edu.rice.cs.hpc.traceviewer.db.remote.DecompressionThread.run ( )

Returns:: The index of a ProcessTimeline that has been uncompressed and is now ready for rendering. Returns null if there aren't any yet for any reason. The unavailability may be a temporary condition that will be resolved in a moment, or it may mean that all available timelines have been processed. Unless this method returns null, it will not return a value that it has returned before.
