    1. R value

Maps the distribution with the given function.

Reverse function

You can optionally define a reverse function. If you don't define reverse function, pmf will throw UnsupportedError.


DiscreteDistribution<R> map<R>(R Function(T value) f,
    {T Function(R value)? reverse}) {
  return _MappedDiscreteDistribution<T, R>(this, f, reverse);
