Class SignedHash

  • All Implemented Interfaces:
    java.util.function.LongUnaryOperator
    public class SignedHash
extends java.lang.Object
implements java.util.function.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.
