## Uses of Class
org.apache.datasketches.quantiles.DoublesSketch

Packages that use DoublesSketch
org.apache.datasketches.quantiles: The quantiles package contains stochastic streaming algorithms that enable single-pass analysis of the distribution of a stream of quantiles.

### Uses of DoublesSketch in org.apache.datasketches.quantiles

Subclasses of DoublesSketch in org.apache.datasketches.quantiles
`class` `CompactDoublesSketch` Compact sketches are inherently read only.
`class` `UpdateDoublesSketch`

Methods in org.apache.datasketches.quantiles that return DoublesSketch
`DoublesSketch` DoublesSketch.`downSample(DoublesSketch srcSketch, int smallerK, org.apache.datasketches.memory.WritableMemory dstMem)` From an source sketch, create a new sketch that must have a smaller K.
`static DoublesSketch` DoublesSketch.`heapify(org.apache.datasketches.memory.Memory srcMem)` Heapify takes the sketch image in Memory and instantiates an on-heap Sketch.
`static DoublesSketch` DoublesSketch.`wrap(org.apache.datasketches.memory.Memory srcMem)` Wrap this sketch around the given Memory image of a DoublesSketch, compact or updatable.

Methods in org.apache.datasketches.quantiles with parameters of type DoublesSketch
`DoublesSketch` DoublesSketch.`downSample(DoublesSketch srcSketch, int smallerK, org.apache.datasketches.memory.WritableMemory dstMem)` From an source sketch, create a new sketch that must have a smaller K.
`static DoublesUnion` DoublesUnion.`heapify(DoublesSketch sketch)` Returns a Heap Union object that has been initialized with the data from the given sketch.
`abstract void` DoublesUnion.`union(DoublesSketch sketchIn)` Iterative union operation, which means this method can be repeatedly called.
