org.apache.datasketches.tuple.Summary
Package
Description
This package contains common tools and methods for the theta,
tuple, tuple/* and fdt packages.
The tuple package contains a number of sketches based on the same
fundamental algorithms of the Theta Sketch Framework and extend these
concepts for whole new families of sketches.
This package is for a generic implementation of the Tuple sketch for single Double value.
This package is for a generic implementation of the Tuple sketch for single Integer value.
This package is for a generic implementation of the Tuple sketch for single String value.
