 long rowOffset)

convertWithTransform

public static <T> CharChunkInputStreamGenerator convertWithTransform(ObjectChunk<T,Values> inChunk,
 long rowOffset,
 ToCharFunction<T> transform)

getInputStream

public ChunkInputStreamGenerator.DrainableColumn getInputStream(StreamReaderOptions options,
 @Nullable
 @Nullable RowSet subset)

Description copied from interface: ChunkInputStreamGenerator

Get an input stream optionally position-space filtered using the provided RowSet.

Parameters:

options - the serializable options for this subscription

subset - if provided, is a position-space filter of source data

Returns:

a single-use DrainableColumn ready to be drained via grpc
