Function Names
hash signatureDescription
This function generates a hash value from the parameters supplied. The intention is to minimize coincidences of two different values resulting to the same hash signature value. Purposes: Fast matching of old vs. new data by just checking the signature values. Great effort has been put in to avoid or minimize colliding signatures, e.g. if two values sharing the same signature. As an example, 'ab' and 'ba' will luckily generate two different signatures. Any number of parameters of any type may be provided, e.g numbers, strings, dates, parameter sets, etc.
