Modifier and TypeMethodDescriptionstatic <T> KllItemsSketch<T>
KllItemsSketch.heapify
(org.apache.datasketches.memory.Memory srcMem, Comparator<? super T> comparator, ArrayOfItemsSerDe<T> serDe) Factory heapify takes a compact sketch image in Memory and instantiates an on-heap sketch.static <T> KllItemsSketch<T>
KllItemsSketch.newHeapInstance
(int k, Comparator<? super T> comparator, ArrayOfItemsSerDe<T> serDe) Create a new heap instance of this sketch with a given parameter k.static <T> KllItemsSketch<T>
KllItemsSketch.newHeapInstance
(Comparator<? super T> comparator, ArrayOfItemsSerDe<T> serDe) Create a new heap instance of this sketch with the default k = 200.static <T> KllItemsSketch<T>
KllItemsSketch.wrap
(org.apache.datasketches.memory.Memory srcMem, Comparator<? super T> comparator, ArrayOfItemsSerDe<T> serDe) Constructs a thin wrapper on the heap around a Memory (or WritableMemory) already initialized with a validated sketch image of a type T consistent with the given comparator and serDe.
