Field Details

prevFlusher

protected transient UpdateCommitter<com.illumon.iris.db.v2.sources.ArraySourceHelper<DBDateTime,long[]>> prevFlusher

The presence of a prevFlusher means that this ArraySource wants to track previous values. If prevFlusher is null, the ArraySource does not want (or does not yet want) to track previous values. Deserialized ArraySources never track previous values.

Constructor Details

DateTimeArraySource

public DateTimeArraySource()

DateTimeArraySource

public DateTimeArraySource(@NotNull
 LongArraySource nanoSource)

Method Details

makeValue

protected DBDateTime makeValue(long nanos)

Specified by:

makeValue in class NanosBasedTimeArraySource<DBDateTime>

toNanos

protected long toNanos(DBDateTime value)

Specified by:

toNanos in class NanosBasedTimeArraySource<DBDateTime>

toDBDateTime

public ColumnSource<DBDateTime> toDBDateTime()

Description copied from interface: ConvertableTimeSource

Convert this source to a DBDateTime source.

Specified by:

toDBDateTime in interface ConvertableTimeSource

Overrides:

toDBDateTime in class NanosBasedTimeArraySource<DBDateTime>

Returns:

a view of this source as a DBDateTime

getCapacity

public final long getCapacity()

Get the capacity of this column source. This number is one higher than the highest key that may be accessed (read or written).

Returns:

The capacity of this column source

makeFillFromContext

public WritableChunkSink.FillFromContext makeFillFromContext(int chunkCapacity)

Description copied from interface: WritableSource

Provide a default, empty WritableChunkSink.FillFromContext for use with our default WritableSource.fillFromChunk(com.illumon.iris.db.v2.sources.WritableChunkSink.FillFromContext, com.illumon.iris.db.v2.sources.chunk.Chunk<? extends com.illumon.iris.db.v2.sources.chunk.Attributes.Values>, com.illumon.iris.db.v2.utils.OrderedKeys).

fillFromChunk

public void fillFromChunk(@NotNull
 WritableChunkSink.FillFromContext context,
 @NotNull
 Chunk<? extends Attributes.Values> src,
 @NotNull
 OrderedKeys orderedKeys)

Description copied from interface: WritableSource

Our default, inefficient, implementation. Inheritors who care should provide a better implementation.

Parameters:

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

src - The source of the data orderedKeys

orderedKeys - An OrderedKeys representing the keys to be written
