Package jsonvalues.gen

Class JsIntGen

java.lang.Object
jsonvalues.gen.JsIntGen
All Implemented Interfaces:
fun.gen.Gen<JsInt>, Function<Random,Supplier<JsInt>>
public final class JsIntGen extends Object implements fun.gen.Gen<JsInt>
Represents a JsInt generator. It can be created using the static factory methods biased() and arbitrary() or, if none of the previous suit your needs, from an integer generator and the function map: 

 import fun.gen.Gen;
 import jsonvalues.JsInt;

 Gen<Integer> intGen = seed -> () -> {...};
 Gen<JsInt> jsIntGen = gen.map(JsInt::of);

Arbitrary generators produce values with a uniform distribution. Biased generators produce potential problematic values with a higher probability, which can help identify and test edge cases.

      Returns:
      A biased JsInt generator.

    • arbitrary

      public static fun.gen.Gen<JsInt> arbitrary()
      Returns a generator that produces values with a uniform distribution.
      Returns:
      A JsInt generator.

    • arbitrary

      public static fun.gen.Gen<JsInt> arbitrary(int min, int max)
      Returns a generator that produces values uniformly distributed over a specified interval.
      Parameters:
      min - The lower bound of the interval (inclusive).
      max - The upper bound of the interval (inclusive).
      Returns:
