Class JsStrGen

java.lang.Object
jsonvalues.gen.JsStrGen
All Implemented Interfaces:
fun.gen.Gen<JsStr>, Function<Random,Supplier<JsStr>>
public final class JsStrGen extends Object implements fun.gen.Gen<JsStr>
Represents a JsStr generator. There are different static factory methods to create all kinds of generators: - One character generators like alphanumeric, digit, letter, and alphabetic. - String generators like digits, letters, alphanumeric, alphabetic, arbitrary, and biased.

The length of the generated strings is distributed uniformly over a specified interval.

The biased generator produces, with higher probability, potential problematic values that usually cause more bugs (empty and blank strings, for example).

If none of the previous factory methods suit your needs, you can still create a JsStr generator from a string generator and the function map: 


 import fun.gen.Gen;
 import jsonvalues.JsStr;

 Gen<String> strGen = seed -> () -> {...};
 Gen<JsStr> jsStrGen = gen.map(JsStr::of);
