Class LongCartesianProduct

java.lang.Object

org.beryx.streamplify.LongIndexedSpliterator<int[],LongCartesianProduct>

org.beryx.streamplify.product.LongCartesianProduct

All Implemented Interfaces:

java.util.Spliterator<int[]>, Streamable<int[],LongCartesianProduct>

public class LongCartesianProduct
extends LongIndexedSpliterator<int[],LongCartesianProduct>

Provides streams of cartesian product tuples.
Can be used when the cardinality of the cartesian product can fit in a long. For bigger cardinalities, a BigIntegerCartesianProduct is needed.
