  • Method Details

    • set

      public abstract void set(int index, long value)
      Set the value at the given index in the array.
      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)
      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.

    • fill

      public void fill(int fromIndex, int toIndex, long val)
      Fill the mutable from fromIndex (inclusive) to toIndex (exclusive) with val.

    • clear

      public void clear()
      Sets all values to 0.

    • save

      public void save(DataOutput out) throws IOException
      Save this mutable into out. Instantiating a reader from the generated data will return a reader with the same number of bits per value.
      Throws:
      IOException
