Packages that use ArrayOfItemsSerDe

Package	Description
org.apache.datasketches.common	This package is for common classes that may be used across all the sketch families.
org.apache.datasketches.frequencies	This package is dedicated to streaming algorithms that enable estimation of the frequency of occurrence of items in a weighted multiset stream of items.
