Method Details

disableGrouping

public void disableGrouping()

Description copied from interface: RegionedColumnSource

Disable the use of grouping for any operation of this source.

Specified by:

disableGrouping in interface RegionedColumnSource<DATA_TYPE>

fillChunk

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

Use the more efficient fill chunk implementation, rather than the default which uses get().

Specified by:

fillChunk in interface ChunkSource<DATA_TYPE>

Specified by:

fillChunk in interface PageStore<DATA_TYPE,ATTR extends Attributes.Values,REGION_TYPE extends ColumnRegion<ATTR>>

Overrides:

fillChunk in class AbstractColumnSource<DATA_TYPE>

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

fillPrevChunk

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

We are immutable, so stick with the efficient fill chunk even when getting prev.

Specified by:

fillPrevChunk in interface ChunkSource.WithPrev<DATA_TYPE>

Overrides:

fillPrevChunk in class AbstractColumnSource<DATA_TYPE>

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

match

@NotNull public Index match(boolean invertMatch, boolean usePrev, boolean caseInsensitive, @NotNull ReadOnlyIndex startingIndex, Object... keys)

Description copied from interface: ColumnSource

Produce an index of rows derived from the 'startingIndex' index that match the input set of keys (taking into account invert, and case sensitivity).

Specified by:

match in interface ColumnSource<DATA_TYPE>

Overrides:

match in class AbstractColumnSource<DATA_TYPE>

Parameters:

invertMatch - If the match should be inverted

usePrev - if previous values should be used

caseInsensitive - if the match should be case insensitive

startingIndex - the index of rows to match

keys - the keys to match

Returns:

an index which is the subset of rows from 'startingIndex' that match the input set of keys
