Class JsDoubleGen

java.lang.Object
jsonvalues.gen.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.

  • Method Details

    • biased

      public static fun.gen.Gen<JsDouble> biased()
      returns a biased generators that produces, with higher probability, potential problematic values that usually cause more bugs. These values are: 
       - Long.MIN_VALUE
 - Integer.MIN_VALUE
 - Short.MIN_VALUE
 - Byte.MIN_VALUE
 -  0
 - Long.MAX_VALUE
 - Integer.MAX_VALUE
 - Short.MAX_VALUE
 - Byte.MAX_VALUE
      Returns:
      a biased JsDouble generator

    • 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
