Class 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 JsInstant 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<JsInteger> jsIntGen = gen.map(JsInt::of)

    Arbitrary generators produces uniformed distributions of values. Biased generators produces, with higher probability, potential problematic values that usually cause more bugs.

      • arbitrary

        public static fun.gen.Gen<JsInt> arbitrary()
        Returns a generator that produces values uniformly distributed
        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 - lower bound of the interval (inclusive)
        max - upper bound of the interval (inclusive)
        Returns:
        a biased JsInt generator

      • biased

        public static fun.gen.Gen<JsInt> biased​(int min,
                                        int max)
        returns a biased generators that produces, with higher probability, potential problematic values that usually cause more bugs. These values are: 
         - the lower bound of the interval
 - the upper bound of the interval
        and the following numbers provided that they are between the specified interval: 
         - Integer.MIN_VALUE
 - Short.MIN_VALUE
 - Byte.MIN_VALUE
 - 0
 - Integer.MAX_VALUE
 - Short.MAX_VALUE
 - Byte.MAX_VALUE
        Parameters:
        min - lower bound of the interval (inclusive)
        max - upper bound of the interval (inclusive)
        Returns:
        a biased JsInt generator

        Specified by:
        apply in interface Function<Random,​Supplier<JsInt>>
        Parameters:
        seed - the generator seed
        Returns:
        a JsInt supplier
