|
* The hash code generation is based on the public domain MurmurHash3 from Austin Appleby:
|
|
* http://code.google.com/p/smhasher/source/browse/trunk/MurmurHash3.cpp
|
|
*
|
|
* We use only the 32 bit variant because the 2 produce different result while
|
|
* we need to produce the same result regardless of the architecture as
|
|
* clients can be both 64 or 32 bit at the same time.
