Function Documentation

combine()

void combine ( size_t &  combinedHash, size_t  additionalHash  )

inline

meld the additional hash value into the given base hash value.

This is the standard formula used by Lib-Boost to combine the hash values of parts into a composite, and is based on the Murmur-2.64A hash algorithm.
