public class IntegerSingleValueSource
extends SingleValueColumnSource<Integer>
implements MutableColumnSourceGetDefaults.ForInt

Single value source for Integer.

The C-haracterSingleValueSource is replicated to all other types with com.illumon.iris.db.v2.sources.Replicate. (C-haracter is deliberately spelled that way in order to prevent Replicate from altering this very comment).

set in class SingleValueColumnSource<Integer>

set

public final void set(int value)

Overrides:

set in class SingleValueColumnSource<Integer>

set

public final void set(long key, int value)

Specified by:

set in interface WritableSource<Integer>

setNull

getInt

public final int getInt(long index)

Description copied from interface: ElementSource

Get the value at the index as an int.

Specified by:

getInt in interface ElementSource<Integer>

Parameters:

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

Returns:

the int at the index, null values are represented by QueryConstants.NULL_INT

getPrevInt

public final int getPrevInt(long index)

Description copied from interface: ElementSource

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

Specified by:

Specified by:

copy in interface WritableSource<Integer>

fillFromChunk

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

Description copied from interface: WritableSource

Specified by:

fillFromChunk in interface WritableChunkSink<Attributes.Values>

Specified by:

fillFromChunk in interface WritableSource<Integer>

Parameters:

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

Specified by:

fillFromChunkUnordered in interface WritableChunkSink<Attributes.Values>

Specified by:

fillFromChunkUnordered in interface WritableSource<Integer>

Parameters:

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

src - The source of the data orderedKeys

keys - A LongChunk representing the keys to be written
