Package org.n52.janmayen.function

Interface ThrowingConsumer<A,X extends Exception>

Type Parameters:

A - the type of the input to the operation

X - the type of the exception the operation might throw

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 ThrowingConsumer<A,X extends Exception>

Represents an operation that accepts a single input argument and returns no result. Unlike most other functional interfaces, Consumer is expected to operate via side-effects.

Method Summary

Modifier and Type	Method	Description
void	accept(A t)	Performs this operation on the given argument.
default ThrowingConsumer<A,X>	andThen(ThrowingConsumer<? super A,? extends X> after)	Returns a composed Consumer that performs, in sequence, this operation followed by the after operation.
default ThrowingRunnable<X>	curry(A t)	Create a ThrowingRunnable by currying the parameter.
default <T> ThrowingConsumer<T,X>	map(ThrowingFunction<? super T,? extends A,X> fun)	Change the type of the parameter using the supplied mapper

Method Detail

accept

void accept(A t)
     throws X extends Exception

Performs this operation on the given argument.

Parameters:

t - the input argument

Throws:

X - if an error occurs

X extends Exception

andThen

default ThrowingConsumer<A,X> andThen(ThrowingConsumer<? super A,? extends X> after)

Returns a composed Consumer that performs, in sequence, this operation followed by the after operation. If performing either operation throws an exception, it is relayed to the caller of the composed operation. If performing this operation throws an exception, the after operation will not be performed.

Parameters:

after - the operation to perform after this operation

Returns:

a composed Consumer that performs in sequence this operation followed by the after operation

Throws:

NullPointerException - if after is null

curry

default ThrowingRunnable<X> curry(A t)

Create a ThrowingRunnable by currying the parameter.

Parameters:

t - the constant parameter

Returns:

the runnable

map

default <T> ThrowingConsumer<T,X> map(ThrowingFunction<? super T,? extends A,X> fun)

Change the type of the parameter using the supplied mapper

Type Parameters:

T - the new input type of the operation

Parameters:

fun - the mapper

Returns:

the consumer
