const MBSpill * MBSpillAccessor::LoadSpill (  VldTimeStamp  vts,
int  which = 0
) 
 

Get the spill closest to the given VldTimeStamp.

Returns the MBSpill nearest to the given time stamp or 0 if none could be found.

which < 0 returns the nearest spill before the given time which = 0 returns the nearest spill (same as LoadSpill) which > 0 returns the nearest spill after the given time
