    • getObject

      public T getObject​(long elementIndex)
      Description copied from interface: ColumnRegionObject
      Get a single object from this region.
      Parameters:
      elementIndex - Element (object) index in the table's address space
      Returns:
      The object value at the specified element (object) index

    • getObject

      public T getObject​(@NotNull ChunkSource.FillContext context, long elementIndex)
      Description copied from interface: ColumnRegionObject
      Get a single object from this region.
      Parameters:
      context - A ColumnRegionFillContext to enable resource caching where suitable, with current region index pointing to this region
      elementIndex - Element (object) index in the table's address space
      Returns:
      The object value at the specified element (object) index

    • fillChunkAppend

      public void fillChunkAppend​(@NotNull ChunkSource.FillContext fillContext, @NotNull WritableChunk<? super ATTR> destination, @NotNull OrderedKeys orderedKeys)
      Description copied from interface: Page.WithDefaults
      Appends the values referenced by orderKeys onto destination. orderKeys are assumed to be entirely contained on this Page.

    • length

      public long length()
      Returns:
      the length of this page.

    • releaseCachedResources

      @OverridingMethodsMustInvokeSuper public void releaseCachedResources()
      Description copied from interface: Releasable
      Release any resources held for caching purposes. Implementations need not guarantee that they are safe for normal use concurrently with invocations of this method.

    • makeFillContext

      public ChunkSource.FillContext makeFillContext​(int chunkCapacity, SharedContext sharedContext)
      Description copied from interface: FillContextMaker
      Allocate a new ChunkSource.FillContext for filling chunks from this FillContextMaker, typically a ChunkSource.
      Parameters:
      chunkCapacity - The maximum size of any WritableChunk that will be filled with this context
      sharedContext - Shared store of intermediate results.
      Returns:
      A context for use with fill operations
