Package org.apache.datasketches.hash

package org.apache.datasketches.hash
The hash package contains a high-performing and extended Java implementations of Austin Appleby's 128-bit MurmurHash3 hash function originally coded in C. This core MurmurHash3.java class is used throughout many of the sketch classes for consistency and as long as the user specifies the same seed will result in coordinated hash operations. This package also contains an adaptor class that extends the basic class with more functions commonly associated with hashing.
