  • Method Details

    • fillChunk

      public void fillChunk(@NotNull ChunkSource.FillContext context, @NotNull @NotNull WritableChunk<? super Values> destination, @NotNull @NotNull RowSequence rowSequence)
      Description copied from interface: ChunkSource
      Populates the given destination chunk with data corresponding to the keys from the given RowSequence.
      Specified by:
      fillChunk in interface ChunkSource<Values>
      Overrides:
      fillChunk in class AbstractColumnSource<String>
      Parameters:
      context - A context containing all mutable/state related data used in retrieving the Chunk.
      destination - The chunk to be populated according to rowSequence. No assumptions shall be made about the size of the chunk shall be made. The chunk will be populated from position [0,rowSequence.size()).
      rowSequence - An RowSequence representing the keys to be fetched
    • get

      public final String get(long rowKey)
      Description copied from interface: ElementSource
      Get the value from the source. This may return boxed values for basic types. RowKeys that are not present are undefined.
      Specified by:
      get in interface ElementSource<String>
      Parameters:
      rowKey - the location in key space to get the value from.
      Returns:
      the value at the rowKey, potentially null.
