## Interface FailableBiFunction<T,U,R,E extends Throwable>

- Type Parameters:
    `T` - Input type 1.
    `U` - Input type 2.
    `R` - Return type.
    `E` - Thrown exception.
  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 FailableBiFunction<T,U,R,E extends Throwable>

  A functional interface like `BiFunction` that declares a `Throwable`.
  Since:

- - ### Field Detail

    - #### NOP

          static final FailableBiFunction NOP

      NOP singleton

  - ### Method Detail

    - #### nop

          static <T,U,R,E extends Throwable> FailableBiFunction<T,U,R,E> nop()

      Returns The NOP singleton.
      Type Parameters:
        `T` - Consumed type 1.
        `U` - Consumed type 2.
        `R` - Return type.
        `E` - Thrown exception.
      Returns:
        The NOP singleton.

    - #### andThen

          default <V> FailableBiFunction<T,U,V,E> andThen(FailableFunction<? super R,? extends V,E> after)

      Returns a composed `FailableBiFunction` that like `BiFunction.andThen(Function)`.
      Type Parameters:
        `V` - the output type of the `after` function, and of the composed function.
      Parameters:
        `after` - the operation to perform after this one.
      Returns:
        a composed `FailableBiFunction` that like `BiFunction.andThen(Function)`.
      Throws:
        `NullPointerException` - when `after` is null.

    - #### apply

          R apply(T input1,
                  U input2)
           throws E extends Throwable

      Applies this function.
      Parameters:
        `input1` - the first input for the function
        `input2` - the second input for the function
      Returns:
        the result of the function
      Throws:
        `E` - Thrown when the function fails.
        `E extends Throwable`
