Interface TextRandomProvider

public interface TextRandomProvider

TextRandomProvider implementations are used by RandomStringGenerator as a source of randomness. It is highly recommended that the Apache Commons RNG library be used to provide the random number generation.

When using Java 8 or later, TextRandomProvider is a functional interface and need not be explicitly implemented. For example: 

 
 UniformRandomProvider rng = RandomSource.create(...);
 RandomStringGenerator gen = new RandomStringGenerator.Builder()
     .usingRandom(rng::nextInt)
     // additional builder calls as needed
     .build();
