IntervalListScatterer
public class IntervalListScattererByIntervalCount extends Object implements IntervalListScatterer
ScattersIntervalList
by interval count so that resultingIntervalList
's have the same number of intervals in them. An exception is made for the final interval list, which will always contain at least this number of intervals, but may also contain the remainder.

Method Detail

intervalWeight
public long intervalWeight(htsjdk.samtools.util.Interval interval)
Description copied from interface:IntervalListScatterer
A method that defines the "weight" of an interval list for the purpose of scattering. The class will attempt to create sublists that all have similar weights.- Specified by:
intervalWeight
in interfaceIntervalListScatterer
-
listWeight
public long listWeight(htsjdk.samtools.util.IntervalList intervalList)
Description copied from interface:IntervalListScatterer
A method that defines the "weight" of an interval for the purpose of scattering. The class will attempt to create sublists that all have similar weights. This method need to estimate the change in any sublists weight due to the possible of the provided interval.- Specified by:
listWeight
in interfaceIntervalListScatterer
-
takeSome
public List<htsjdk.samtools.util.Interval> takeSome(htsjdk.samtools.util.Interval interval, long idealSplitWeight, long currentSize, double projectSizeOfRemaining)
Description copied from interface:IntervalListScatterer
Figure out how much of the input interval to put into current list and how much to leave for the next interval list.- Specified by:
takeSome
in interfaceIntervalListScatterer
- Returns:
- a list of two (possibly null) elements. The first element should be added to the current interval list, the second should be offered to the next interval list.
-
deduceIdealSplitWeight
public int deduceIdealSplitWeight(htsjdk.samtools.util.IntervalList intervalList, int nCount)
Description copied from interface:IntervalListScatterer
A method that determines the ideal target "weight" of the output IntervalList.- Specified by:
deduceIdealSplitWeight
in interfaceIntervalListScatterer
- Parameters:
intervalList
- theIntervalList
that is about to get splitnCount
- the scatter count into which to split intervalList- Returns:
- The ideal "weight" of the output
