Constructor Details

BooleanAsByteColumnSource

public BooleanAsByteColumnSource(ColumnSource<Boolean> alternateColumnSource)

Method Details

getByte

public byte getByte(long index)

Description copied from interface: ElementSource

Get the value at the index as a byte.

Specified by:

getByte in interface ElementSource<Byte>

Parameters:

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

Returns:

the boolean at the index, null values are represented by QueryConstants.NULL_BYTE

getPrevByte

public byte getPrevByte(long index)

Description copied from interface: ElementSource

Get the previous value at the index as a byte. See ElementSource.getPrev(long) for more details.

Specified by:

getPrevByte in interface ElementSource<Byte>

Parameters:

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

Returns:

the previous boolean at the index, null values are represented by QueryConstants.NULL_BYTE

isImmutable

public boolean isImmutable()

Description copied from interface: ColumnSource

Determine if this column source is immutable, meaning that the values at a given index key never change.

Specified by:

isImmutable in interface ColumnSource<Byte>

Specified by:

isImmutable in interface MutableColumnSource<Byte>

Returns:

true if the values at a given index of the column source never change, false otherwise

allowsReinterpret

public <ALTERNATE_DATA_TYPE> boolean allowsReinterpret(@NotNull Class<ALTERNATE_DATA_TYPE> alternateDataType)

Description copied from interface: ColumnSource

Test if a reinterpret call will succeed.

Specified by:

allowsReinterpret in interface ColumnSource<Byte>

Overrides:

allowsReinterpret in class AbstractColumnSource<Byte>

Type Parameters:

ALTERNATE_DATA_TYPE - the dataType to inquire about

Parameters:

alternateDataType - The alternative type to consider

Returns:

If a reinterpret on this column source with the supplied alternateDataType will succeed.

doReinterpret

public <ALTERNATE_DATA_TYPE> ColumnSource<ALTERNATE_DATA_TYPE> doReinterpret(@NotNull Class<ALTERNATE_DATA_TYPE> alternateDataType) throws IllegalArgumentException

Description copied from class: AbstractColumnSource

Supply allowed reinterpret results. The default implementation handles the most common case to avoid code duplication.

Overrides:

doReinterpret in class AbstractColumnSource<Byte>

Type Parameters:

ALTERNATE_DATA_TYPE - the dataType to reinterpret to

Parameters:

alternateDataType - The alternate data type

Returns:

The resulting ColumnSource

Throws:

IllegalArgumentException

makeFillContext

public ChunkSource.FillContext makeFillContext(int chunkCapacity, SharedContext sharedContext)

Description copied from interface: FillContextMaker

Allocate a new ChunkSource.FillContext for filling chunks from this FillContextMaker, typically a ChunkSource.

Specified by:

makeFillContext in interface DefaultChunkSource<Attributes.Values>

Specified by:

makeFillContext in interface FillContextMaker

Parameters:

chunkCapacity - The maximum size of any WritableChunk that will be filled with this context

sharedContext - Shared store of intermediate results.

Returns:

A context for use with fill operations

fillChunk

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

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)

Description copied from interface: ChunkSource.WithPrev

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

Specified by:

fillPrevChunk in interface ChunkSource.WithPrev<Attributes.Values>

Overrides:

fillPrevChunk in class AbstractColumnSource<Byte>

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
