FailableFunction (org.pipecraft.pipes:pipes-core 0.9 API)

Type Parameters:

T - The type of the input

R - The type of the output

E - The exception type

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 FailableFunction<T,R,E extends Exception>
```
A function that may fail with a checked exception during the execution of the apply(..) method.

Modifier and Type	Method	Description
`default <V> FailableFunction<T,V,E>`	`andThen(FailableFunction<? super R,? extends V,E> after)`	Similar to Function.andThen(..), but works with `FailableFunction`
`R`	`apply(T v)`	Applies the function
`default <V> FailableFunction<V,R,E>`	`compose(FailableFunction<? super V,? extends T,E> before)`	Similar to Function.compose(..), but works with `FailableFunction`
`static <T,E extends Exception> FailableFunction<T,T,E>`	`identity()`	Similar to Function.identity(), but returns a `FailableFunction`
