    • get

      public long get(int index)
      Description copied from class: PackedInts.Reader
      Get the long at the given index. Behavior is undefined for out-of-range indices.
      Specified by:
      get in class PackedInts.Reader

    • set

      public void set(int index, long value)
      Description copied from class: PackedInts.Mutable
      Set the value at the given index in the array.
      Specified by:
      set in class PackedInts.Mutable
      Parameters:
      index - where the value should be positioned.
      value - a value conforming to the constraints set by the array.

    • ramBytesUsed

      public long ramBytesUsed()
      Description copied from interface: Accountable
      Return the memory usage of this object in bytes. Negative values are illegal.
