Class RandomProvider

java.lang.Object
mocka.random.RandomProvider
public class RandomProvider extends Object
Thread-safe singleton provider for generating random values.

This class serves as a facade for random number generation, delegating to ThreadLocalRandomIndexProvider for thread-safe random value generation. It provides convenient methods for generating various primitive types with different range constraints.
