Module io.smallrye.mutiny

Package io.smallrye.mutiny.unchecked

Interface UncheckedFunction<T,R>

Type Parameters:

T - the type of the input to the function

R - the type of the result of the function

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 UncheckedFunction<T,R>

Represents a function that accepts one argument and produces a result.

The operation can throw Exceptions.

Method Summary

Modifier and Type	Method	Description
default <V> UncheckedFunction<T,V>	andThen(UncheckedFunction<? super R,? extends V> 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> UncheckedFunction<V,R>	compose(UncheckedFunction<? super V,? extends T> before)	Returns a composed function that first applies the before function to its input, and then applies this function to the result.
static <T,R> UncheckedFunction<T,R>	from(java.util.function.Function<T,R> function)	Creates a UncheckedBiConsumer from an existing Function
default java.util.function.Function<T,R>	toFunction()

Method Detail

from

static <T,R> UncheckedFunction<T,R> from(java.util.function.Function<T,R> function)

Creates a UncheckedBiConsumer from an existing Function

Type Parameters:

T - the type of the input to the function

R - the type of the result of the function

Parameters:

function - the function

Returns:

the created UncheckedBiConsumer

apply

R apply(T t)
 throws java.lang.Exception

Applies this function to the given argument.

Parameters:

t - the function argument

Returns:

the function result

Throws:

java.lang.Exception - if anything wrong happen

toFunction

default java.util.function.Function<T,R> toFunction()

Returns:

a Function executing this UncheckedFunction. If the operation throws an exception, the exception is rethrown, wrapped in a RuntimeException if needed.

compose

default <V> UncheckedFunction<V,R> compose(UncheckedFunction<? super V,? extends T> 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:

java.lang.NullPointerException - if before is null

andThen(UncheckedFunction)

andThen

default <V> UncheckedFunction<T,V> andThen(UncheckedFunction<? super R,? extends V> 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:

java.lang.NullPointerException - if after is null
