public class ArrayOfDoublesAnotBImpl extends ArrayOfDoublesAnotB
Computes a set difference, A-AND-NOT-B, of two ArrayOfDoublesSketches.

This class includes a stateless operation as follows:

CompactTupleSketch csk = anotb.aNotB(ArrayOfDoublesSketch skA, ArrayOfDoublesSketch skB);

  • Method Details

    • update

      public void update(ArrayOfDoublesSketch skA, ArrayOfDoublesSketch skB)
      Description copied from class: ArrayOfDoublesAnotB
      Perform A-and-not-B set operation on the two given sketches. A null sketch is interpreted as an empty sketch. This is not an accumulating update. Calling update() more than once without calling getResult() will discard the result of previous update(). Both input sketches must have the same numValues.
      Specified by:
      update in class ArrayOfDoublesAnotB
      Parameters:
      skA - The incoming sketch for the first argument
      skB - The incoming sketch for the second argument

    • getResult

      public ArrayOfDoublesCompactSketch getResult()
      Description copied from class: ArrayOfDoublesAnotB
      Gets the result of this operation in the form of a ArrayOfDoublesCompactSketch
      Specified by:
      getResult in class ArrayOfDoublesAnotB
      Returns:
      compact sketch representing the result of the operation

    • getResult

      public ArrayOfDoublesCompactSketch getResult(MemorySegment dstSeg)
      Description copied from class: ArrayOfDoublesAnotB
      Gets the result of this operation in the form of a ArrayOfDoublesCompactSketch
      Specified by:
      getResult in class ArrayOfDoublesAnotB
      Parameters:
      dstSeg - MemorySegment for the result (can be null)
      Returns:
      compact sketch representing the result of the operation (off-heap if MemorySegment is provided)
