Method Detail

forValue

public BitmapColumnIndex forValue(@Nullable
                                  String value)

Description copied from interface: StringValueSetIndex

Get the ImmutableBitmap corresponding to the supplied value

Specified by:

forValue in interface StringValueSetIndex

forSortedValues

public BitmapColumnIndex forSortedValues(SortedSet<String> values)

Description copied from interface: StringValueSetIndex

Get an Iterable of ImmutableBitmap corresponding to the specified set of values (if they are contained in the underlying column). The set must be sorted using Comparators.naturalNullsFirst().

Specified by:

forSortedValues in interface StringValueSetIndex

forSortedValuesUtf8

public BitmapColumnIndex forSortedValuesUtf8(SortedSet<ByteBuffer> valuesUtf8)

Description copied from interface: Utf8ValueSetIndex

Get an Iterable of ImmutableBitmap corresponding to the specified set of values (if they are contained in the underlying column). The set must be sorted using ByteBufferUtils.utf8Comparator().

Specified by:

forSortedValuesUtf8 in interface Utf8ValueSetIndex
