Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`hash(byte[] payload)`	Hashes a byte array efficiently.
`int`	`hash(int hashcode)`	An incremental version of the hash function, that spreads a pre-calculated hash code, such as one derived from `Object.hashCode()`.
`int`	`hash(Object o)`	A helper that calculates the hashcode of an object, choosing the optimal mechanism of hash calculation after considering the type of the object (byte array, String or Object).
