Documentation

Currently, there is only one hash method - v3. It generates MurmurHash v3. As Brightscript has only 32 or 64 signed values (Integer and LongInteger) this supports only 32-bit generation.

MurmurHash().v3(key, seed)

params:

• key - String or ByteArray to be hashed
• seed - accepts LongInteger, but it can be also an Integer

returns: (LongInteger) hashed value LongInteger value hash
