Type Parameters:

T - the type of the input to the function

R - the type of the result of the function

EXTYPE - 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 IThrowingFunction<T,R,EXTYPE extends Throwable>
```
Represents a function that accepts one argument and produces a result and may throw an Exception.
This is a functional interface whose functional method is apply(Object).

Since:

8.3.1

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default <V> IThrowingFunction<T,V,EXTYPE>`	`andThen(IThrowingFunction<? super R,? extends V,? extends EXTYPE> after)`	Returns a composed function that first applies this function to its input, and then applies the `after` function to the result.
`R`	`apply(T t)`	Applies this function to the given argument.
`default <V> IThrowingFunction<V,R,EXTYPE>`	`compose(IThrowingFunction<? super V,? extends T,? extends EXTYPE> before)`	Returns a composed function that first applies the `before` function to its input, and then applies this function to the result.

```
R apply(T t)
 throws EXTYPE extends Throwable
```
    Applies this function to the given argument.
    
    Parameters:
    
    t - the function argument
    
    Returns:
    
    the function result
    
    Throws:
    
    EXTYPE - In case it is needed
    
    EXTYPE extends Throwable
  - compose

@Nonnull
default <V> IThrowingFunction<V,R,EXTYPE> compose(@Nonnull
                                                              IThrowingFunction<? super V,? extends T,? extends EXTYPE> before)
```
    Returns a composed function that first applies the before function to its input, and then applies this function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.
    
    Type Parameters:
    
    V - the type of input to the before function, and to the composed function
    
    Parameters:
    
    before - the function to apply before this function is applied
    
    Returns:
    
    a composed function that first applies the before function and then applies this function
    
    Throws:
    
    NullPointerException - if before is null

default <V> IThrowingFunction<T,V,EXTYPE> andThen(@Nonnull
                                                              IThrowingFunction<? super R,? extends V,? extends EXTYPE> after)
```
    Returns a composed function that first applies this function to its input, and then applies the after function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.
    
    Type Parameters:
    
    V - the type of output of the after function, and of the composed function
    
    Parameters:
    
    after - the function to apply after this function is applied
    
    Returns:
    
    a composed function that first applies this function and then applies the after function
    
    Throws:
    
    NullPointerException - if after is null
