Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (murmurhash-roku) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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
