  • Method Details

    • fillChunkUnordered

      void fillChunkUnordered(@NotNull ChunkSource.FillContext context, @NotNull @NotNull WritableChunk<? super ATTR> dest, @NotNull @NotNull LongChunk<? extends RowKeys> keys)
      Populates a contiguous portion of the given destination chunk with data corresponding to the keys from the given LongChunk.

      It behaves as if the following code were executed: 

       destination.setSize(keys.size());
 for (int ii = 0; ii < keys.size(); ++ii) {
     destination.set(ii, get(keys.get(ii)));
 }
      Parameters:
      context - A context containing all mutable/state related data used in retrieving the Chunk.
      dest - The chunk to be populated according to keys
      keys - A chunk of individual, not assumed to be ordered keys to be fetched

    • fillPrevChunkUnordered

      void fillPrevChunkUnordered(@NotNull ChunkSource.FillContext context, @NotNull @NotNull WritableChunk<? super ATTR> dest, @NotNull @NotNull LongChunk<? extends RowKeys> keys)
      Populates a contiguous portion of the given destination chunk with prev data corresponding to the keys from the given LongChunk.

      It behaves as if the following code were executed: 

       destination.setSize(keys.size());
 for (int ii = 0; ii < keys.size(); ++ii) {
     destination.set(ii, getPrev(keys.get(ii)));
 }
      Parameters:
      context - A context containing all mutable/state related data used in retrieving the Chunk.
      dest - The chunk to be populated according to keys
      keys - A chunk of individual, not assumed to be ordered keys to be fetched

    • providesFillUnordered

      boolean providesFillUnordered()
      Returns true if this column source can efficiently provide an unordered fill. If this method returns false, then fillChunkUnordered and fillPrevChunkUnordered may throw an UnsupportedOperationException.
      Returns:
      if this column source can provide an unordered fill
