Class SignedHash

java.lang.Object

io.virtdata.basicsmappers.from_long.to_long.SignedHash

All Implemented Interfaces:

LongUnaryOperator

public class SignedHash
extends Object
implements LongUnaryOperator

This uses the Murmur3F (64-bit optimized) version of Murmur3, not as a checksum, but as a simple hash. It doesn't bother pushing the high-64 bits of input, since it only uses the lower 64 bits of output. Unlike the other hash functions, this one may return positive as well as negative values.
