public class CharacterSingleValueSource
extends SingleValueColumnSource<Character>
implements MutableColumnSourceGetDefaults.ForChar

Single value source for Character.

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).

Method Details

set

public final void set(Character value)

Overrides:

set in class SingleValueColumnSource<Character>

set

public final void set(char value)

Overrides:

set in class SingleValueColumnSource<Character>

set

public final void set(long key,
 char value)

Specified by:

set in interface WritableSource<Character>

setNull

public final void setNull(long key)

Specified by:

setNull in interface WritableSource<Character>

setNull

public final void setNull(OrderedKeys keys)

getChar

public final char getChar(long index)

Description copied from interface: ElementSource

Get the value at the index as a char.

Specified by:

getChar in interface ElementSource<Character>

Parameters:

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

Returns:

the char at the index, null values are represented by QueryConstants.NULL_CHAR

getPrevChar

public final char getPrevChar(long index)

Description copied from interface: ElementSource

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

Specified by:

getPrevChar in interface ElementSource<Character>

Parameters:

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

Returns:

the previous char at the index, null values are represented by QueryConstants.NULL_CHAR

copy

 long sourceKey,
 long destKey)

Specified by:

copy in interface WritableSource<Character>

fillFromChunk

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

Specified by:

fillFromChunkUnordered in interface WritableChunkSink<Attributes.Values>

Specified by:

fillFromChunkUnordered in interface WritableSource<Character>

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
