Package io.nosqlbench.virtdata.library.basics.shared.from_long.to_long

Class HashInterval

java.lang.Object
io.nosqlbench.virtdata.library.basics.shared.from_long.to_long.HashInterval
All Implemented Interfaces:
java.util.function.LongUnaryOperator
public class HashInterval
extends java.lang.Object
implements java.util.function.LongUnaryOperator
Return a value within a range, pseudo-randomly, using interval semantics, where the range of values return does not include the last value. This function behaves exactly like HashRange except for the exclusion of the last value. This allows you to stack intervals using known reference points without duplicating or skipping any given value. You can specify hash intervals as small as a single-element range, like (5,6), or as wide as the relevant data type allows.
