Class JsDoubleGen

  • All Implemented Interfaces:
    fun.gen.Gen<JsDouble>, Function<Random,​Supplier<JsDouble>>
    public final class JsDoubleGen
extends Object
implements fun.gen.Gen<JsDouble>
    Represents a JsDouble generator. It can be created using the static factory methods biased and arbitrary or, if none of the previous suit your needs, from a double generator and the function map: 
    
      import fun.gen.Gen;
      import jsonvalues.JsDouble;

      Gen<Double> doubleGen = seed -> () -> {...};
      Gen<JsDouble> jsDoubleGen = gen.map(JsDouble::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<JsDouble> arbitrary()
        Returns a generator that produces values uniformly distributed
        Returns:
        a JsDouble generator

      • biased

        public static fun.gen.Gen<JsDouble> biased​(double min,
                                           double 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: 
         - Long.MIN_VALUE
 - Integer.MIN_VALUE
 - Short.MIN_VALUE
 - Byte.MIN_VALUE
 - 0
 - Integer.MAX_VALUE
 - Short.MAX_VALUE
 - Byte.MAX_VALUE
 - Long.MAX_VALUE
        Parameters:
        min - lower bound of the interval (inclusive)
        max - upper bound of the interval (inclusive)
        Returns:
        a biased JsDouble generator

      • arbitrary

        public static fun.gen.Gen<JsDouble> arbitrary​(double min,
                                              double 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 JsDouble generator

      • apply

        public Supplier<JsDouble> apply​(Random seed)
        Returns a supplier from the specified seed that generates a new JsDouble each time it's called
        Specified by:
        apply in interface Function<Random,​Supplier<JsDouble>>
        Parameters:
        seed - the generator seed
        Returns:
        a JsDouble supplier
