Method Details

fillChunk

public void fillChunk(@NotNull
 ChunkSource.FillContext context,
 @NotNull
 @NotNull WritableChunk<? super Attributes.Values> destination,
 @NotNull
 @NotNull OrderedKeys orderedKeys)

Description copied from interface: ChunkSource

Populates the given destination chunk with data corresponding to the keys from the given OrderedKeys.

Specified by:

fillChunk in interface ChunkSource<Attributes.Values>

Overrides:

fillChunk in class AbstractColumnSource<Double>

Parameters:

context - A context containing all mutable/state related data used in retrieving the Chunk.

destination - The chunk to be populated according to orderedKeys. No assumptions shall be made about the size of the chunk shall be made. The chunk will be populated from position [0,orderedKeys.size()).

orderedKeys - An OrderedKeys representing the keys to be fetched

getDouble

public final double getDouble(long index)

Description copied from interface: ElementSource

Get the value at the index as a double.

Specified by:

getDouble in interface ElementSource<Double>

Parameters:

index - the location in index space to get the value from.

Returns:

the double at the index, null values are represented by QueryConstants.NULL_DOUBLE
