All Implemented Interfaces:

ChunkSource<Attributes.Values>, ChunkSource.WithPrev<Attributes.Values>, DefaultChunkSource<Attributes.Values>, DefaultChunkSource.WithPrev<Attributes.Values>, FillContextMaker, GetContextMaker, ColumnSource<LocalTime>, ColumnSourceGetDefaults.ForObject<LocalTime>, ElementSource<LocalTime>, MutableColumnSource<LocalTime>, MutableColumnSourceGetDefaults.ForObject<LocalTime>, Releasable, TupleExporter<LocalTime>, TupleSource<LocalTime>, Serializable

public class LocalTimeWrapperSource
extends AbstractColumnSource<LocalTime>
implements MutableColumnSourceGetDefaults.ForObject<LocalTime>

A ColumnSource for LocalTimes that is backed by an inner ColumnSource of ZonedDateTime. Note that no special handling is done for timezones. The returned local time will be in the zone of each inner ZonedDateTime.

LocalTimeWrapperSource

public LocalTimeWrapperSource(ColumnSource<ZonedDateTime> inner, ZoneId zone)

Method Details

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<LocalTime>

Overrides:

allowsReinterpret in class AbstractColumnSource<LocalTime>

Parameters:

alternateDataType - The alternative type to consider

Returns:

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

doReinterpret

protected <ALTERNATE_DATA_TYPE> ColumnSource<ALTERNATE_DATA_TYPE> doReinterpret(@NotNull Class<ALTERNATE_DATA_TYPE> alternateDataType)

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<LocalTime>

Parameters:

alternateDataType - The alternate data type

Returns:

The resulting ColumnSource

get

@Nullable public LocalTime get(long index)

Description copied from interface: ElementSource

Get the value from the source. This may return boxed values for basic types.

Specified by:

get in interface ElementSource<LocalTime>

Parameters:

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

Returns:

the value at the index, potentially null.

getPrev

@Nullable public LocalTime getPrev(long index)

Description copied from interface: ElementSource

Get the previous value at the index. Previous values are used during an LTM update cycle to process changes in data. During normal operation previous values will be identical to current values.

Specified by:

getPrev in interface ElementSource<LocalTime>

Parameters:

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

Returns:

the previous value at the index, or null.

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> dest, @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<LocalTime>

Parameters:

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

dest - 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> dest, @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<LocalTime>

Parameters:

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

dest - 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
