io.virtdata.lfsrs.MetaShift.Func

io.virtdata.basicsmappers.from_long.to_long.Shuffle

All Implemented Interfaces:

LongUnaryOperator

public class Shuffle
extends MetaShift.Func

This function provides a low-overhead shuffling effect without loading elements into memory. It uses a bundled dataset of pre-computed Galois LFSR shift register configurations, along with a down-sampling method to provide amortized virtual shuffling with minimal memory usage.
