setNull

default void setNull(RowSequence orderedKeys)

ensureCapacity

@FinalDefault
default void ensureCapacity(long capacity)

Equivalent to ensureCapacity(capacity, true).

ensureCapacity

void ensureCapacity(long capacity,
 boolean nullFilled)

Ensure that this WritableColumnSource can accept row keys in range [0, capacity).

Parameters:

capacity - The new minimum capacity

nullFilled - Whether data should be "null-filled". If true, get operations at row keys that have not been set will return the appropriate null value; otherwise such gets produce undefined results.

makeFillFromContext

default ChunkSink.FillFromContext makeFillFromContext(int chunkCapacity)

Provide a default, empty ChunkSink.FillFromContext for use with our default fillFromChunk(io.deephaven.engine.table.ChunkSink.FillFromContext, io.deephaven.chunk.Chunk<? extends io.deephaven.chunk.attributes.Values>, io.deephaven.engine.rowset.RowSequence).

Specified by:

makeFillFromContext in interface ChunkSink<T>

fillFromChunk

default void fillFromChunk(@NotNull
 @NotNull ChunkSink.FillFromContext context,
 @NotNull
 @NotNull Chunk<? extends Values> src,
 @NotNull
 @NotNull RowSequence rowSequence)

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

Specified by:

fillFromChunk in interface ChunkSink<T>

Parameters:

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

src - The source of the data rowSequence

rowSequence - An RowSequence representing the keys to be written

fillFromChunkUnordered

default void fillFromChunkUnordered(@NotNull
 @NotNull ChunkSink.FillFromContext context,
 @NotNull
 @NotNull Chunk<? extends Values> src,
 @NotNull
 @NotNull LongChunk<RowKeys> keys)

Description copied from interface: ChunkSink

Fills the ChunkSink with data from the source, with data corresponding to the keys from the given key chunk.

Specified by:

fillFromChunkUnordered in interface ChunkSink<T>

Parameters:

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

src - The source of the data RowSequence

keys - A LongChunk representing the keys to be written
