Constructor Detail

MutableBitSliceIndex

public MutableBitSliceIndex(int maxValue,
                            int minValue,
                            org.roaringbitmap.buffer.MutableRoaringBitmap[] bA,
                            org.roaringbitmap.buffer.MutableRoaringBitmap ebM)

construct a new ImmutableBitSliceIndex from raw slice

Parameters:

maxValue - max value for this bsi

minValue - min value for this bsi

bA - bit slices for this bsi.using MutableRoaringBitmap array express

ebM - exits value bitmap,use MutableRoaringBitmap express

MutableBitSliceIndex

public MutableBitSliceIndex(int minValue,
                            int maxValue)

construct a new MutableBitSliceIndex. Min/Max values are optional. If set to 0 then the underlying BSI will be automatically sized.

MutableBitSliceIndex

public MutableBitSliceIndex()

constructs an auto-sized BSI

Method Detail

runOptimize

public void runOptimize()

RunOptimize attempts to further compress the runs of consecutive values found in the bitmap

hasRunCompression

public boolean hasRunCompression()

addDigit

public void addDigit(org.roaringbitmap.buffer.MutableRoaringBitmap foundSet,
                     int i)

getExistenceBitmap

public org.roaringbitmap.buffer.MutableRoaringBitmap getExistenceBitmap()

getMutableSlice

public org.roaringbitmap.buffer.MutableRoaringBitmap getMutableSlice(int i)

setValue

public void setValue(int columnId,
                     int value)

SetValue sets a value for a given columnID.

Specified by:

setValue in interface BitmapSliceIndex

Parameters:

columnId - columnID

value - the value for columnID

setValues

public void setValues(java.util.List<Pair<java.lang.Integer,java.lang.Integer>> values,
                      java.lang.Integer currentMaxValue,
                      java.lang.Integer currentMinValue)

Description copied from interface: BitmapSliceIndex

setValues will batch set value for this bsi. currentMaxValue/currentMinValue are optional,it's can be compute from input value list. and avoiding bsi expend slice array capacity.

Specified by:

setValues in interface BitmapSliceIndex

add

public void add(MutableBitSliceIndex otherBsi)

add tow bsi index
