Class ToUUID

java.lang.Object

io.nosqlbench.virtdata.library.basics.shared.from_long.to_uuid.ToUUID

All Implemented Interfaces:

LongFunction<UUID>

public class ToUUID
extends Object
implements LongFunction<UUID>

This function creates a non-random UUID in the type 4 version (Random). It always puts the same value in the MSB position of the UUID format. The input value is put in the LSB position. This function is suitable for deterministic testing of scenarios which depend on type 4 UUIDs, but without the mandated randomness that makes testing difficult. Just be aware that the MSB will always contain value 0x0123456789ABCDEFL unless you specify a different long value to pre-fill it with.
