      Performs a case match on this sum type by invoking the mapping function for the matching case with the value of this sum type and returning the result.
      Type Parameters:
      R - Type of the result returned by each mapping function.
      Parameters:
      first - Mapping function for the first case.
      second - Mapping function for the second case.
      third - Mapping function for the third case.
      fourth - Mapping function for the fourth case.
      fifth - Mapping function for the fifth case.
      Returns:
      The value returned by the mapping function for the matching case.

    • match

      public <R> R match(R defaultValue, OneOfN.OneOf5Matcher<R,T1,T2,T3,T4,T5> matcher)
      Performs a case match on this sum type by invoking the mapping function for the matching case with the value of this sum type and returning the result.
      Type Parameters:
      R - Type of the result returned by each mapping function.
      Parameters:
      defaultValue - Value returned when the given matcher has no matching case.
      matcher - Matcher object for each case.
      Returns:
      The value returned by the mapping function for the matching case.

    • mergeFirst

      public OneOfN.OneOf4<T2,T3,T4,T5> mergeFirst(Function<T1,T2> combiner)
      Allows for a multi-stage reduce operation of the cases into a single value. Reduces the number of cases by one by mapping the first to the second case via the given mapping function.
      Parameters:
      combiner - Mapping function that transform the value of the first case into the second case.
      Returns:
      A sum type with one less case.

    • mergeLast

      public OneOfN.OneOf4<T1,T2,T3,T4> mergeLast(Function<T5,T4> combiner)
      Allows for a multi-stage reduce operation of the cases into a single value. Reduces the number of cases by one by mapping the fifth to the fourth case via the given mapping function.
      Parameters:
      combiner - Mapping function that transform the value of the fifth case into the fourth case.
      Returns:
      A sum type with one less case.
