  • Method Details

    • get

      @Nullable public @Nullable WritableLongChunk<T> get()
      Get the underlying chunk.
      Returns:
      the underlying chunk. May be null if the chunk has not been initialized.

    • ensureCapacity

      public WritableLongChunk<T> ensureCapacity(int capacity)
      Ensure the underlying chunk has a capacity of at least capacity, preserving data. The data and size of the returned chunk are undefined. If you must maintain the data, then use ensureCapacityPreserve(int).
      Parameters:
      capacity - the minimum capacity for the chunk.
      Returns:
      the underlying chunk

    • ensureCapacityPreserve

      public WritableLongChunk<T> ensureCapacityPreserve(int capacity)
      Ensure the underlying chunk has a capacity of at least capacity. If the chunk has existing data, then it is copied to the new chunk. If the underlying chunk already exists, then the size of the chunk is the original size. If the chunk did not exist, then the size of the returned chunk is zero.
      Parameters:
      capacity - the minimum capacity for the chunk.
      Returns:
      the underlying chunk
