Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface Shrink<T>
Represents a strategy for producing objects "smaller than" a given object.

  • Method Details

    • shrink

      List<T> shrink(SourceOfRandomness random, Object larger)
      Gives some objects that are "smaller" than a given object.
      Parameters:
      random - source of randomness to use in shrinking, if desired
      larger - the larger object
      Returns:
      objects that are "smaller" than the larger object
