Methods in org.apache.datasketches.quantiles that return ItemsSketch

Modifier and Type	Method	Description
ItemsSketch<T>	ItemsSketch.downSample(int newK)	From an existing sketch, this creates a new sketch that can have a smaller value of K.
static <T> ItemsSketch<T>	ItemsSketch.getInstance(int k, Comparator<? super T> comparator)	Obtains a new instance of an ItemsSketch.
static <T> ItemsSketch<T>	ItemsSketch.getInstance(Comparator<? super T> comparator)	Obtains a new instance of an ItemsSketch using the DEFAULT_K.
static <T> ItemsSketch<T>	ItemsSketch.getInstance(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 ItemsSketch
ItemsSketch<T>	ItemsUnion.getResult()	Gets the result of this Union operation as a copy of the internal state.
ItemsSketch<T>	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 ItemsSketch

Modifier and Type	Method	Description
static <T> ItemsUnion<T>	ItemsUnion.getInstance(ItemsSketch<T> sketch)	Create an instance of ItemsUnion based on ItemsSketch
void	ItemsUnion.update(ItemsSketch<T> sketchIn)	Iterative union operation, which means this method can be repeatedly called.
