  • Method Details

    • 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

    • get

      public int get(int index, long[] arr, int off, int len)
      Description copied from class: PackedInts.Reader
      Bulk get: read at least one and at most len longs starting from index into arr[off:off+len] and return the actual number of values that have been read.
      Overrides:
      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.

    • set

      public int set(int index, long[] arr, int off, int len)
      Description copied from class: PackedInts.Mutable
      Bulk set: set at least one and at most len longs starting at off in arr into this mutable, starting at index. Returns the actual number of values that have been set.
      Overrides:
      set in class PackedInts.Mutable

    • fill

      public void fill(int fromIndex, int toIndex, long val)
      Description copied from class: PackedInts.Mutable

      Overrides:
      fill in class PackedInts.Mutable

    • clear

      public void clear()
      Description copied from class: PackedInts.Mutable
