Uses of ItemsSketch in org.apache.datasketches.quantiles
Methods in org.apache.datasketches.quantiles that return ItemsSketchModifier and TypeMethodDescriptionItemsSketch.downSample(int newK) From an existing sketch, this creates a new sketch that can have a smaller K.static <T> ItemsSketch<T>ItemsSketch.getInstance(Class<T> clazz, int k, Comparator<? super T> comparator) Obtains a new instance of an ItemsSketch.static <T> ItemsSketch<T>ItemsSketch.getInstance(Class<T> clazz, Comparator<? super T> comparator) Obtains a new instance of an ItemsSketch using the DEFAULT_K.static <T> ItemsSketch<T>ItemsSketch.getInstance(Class<T> clazz, org.apache.datasketches.memory.Memory srcMem, Comparator<? super T> comparator, ArrayOfItemsSerDe<T> serDe) Heapifies the given srcMem, which must be a Memory image of a ItemsSketchItemsUnion.getResult()Gets the result of this Union operation as a copy of the internal state.ItemsUnion.getResultAndReset()Gets the result of this Union operation (without a copy) and resets this Union to the virgin state.Methods in org.apache.datasketches.quantiles with parameters of type ItemsSketchModifier and TypeMethodDescriptionstatic <T> ItemsUnion<T>ItemsUnion.getInstance(ItemsSketch<T> sketch) Create an instance of ItemsUnion based on ItemsSketchvoidItemsUnion.union(ItemsSketch<T> sketchIn) Iterative union operation, which means this method can be repeatedly called.
