Interface ThrowingBiConsumer<A,B,X extends Exception>

Type Parameters:

A - the type of the first argument to the operation

B - the type of the second argument to the operation

X - the type of the exception that might be thrown

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 ThrowingBiConsumer<A,B,X extends Exception>

Represents an operation that accepts two input arguments and returns no result. This is the two-arity specialization of Consumer. Unlike most other functional interfaces, BiConsumer is expected to operate via side-effects.

Method Summary

Modifier and Type	Method and Description
void	accept(A t, B u) Performs this operation on the given arguments.
default ThrowingBiConsumer<A,B,X>	andThen(ThrowingBiConsumer<? super A,? super B,? extends X> after) Returns a composed BiConsumer that performs, in sequence, this operation followed by the after operation.
default ThrowingConsumer<B,X>	curryFirst(A t) Get a ThrowingConsumer by currying the first parameter.
default ThrowingConsumer<A,X>	currySecond(B u) Get ThrowingConsumer by currying the second parameter.
default <T> ThrowingBiConsumer<T,B,X>	mapFirst(ThrowingFunction<? super T,? extends A,X> fun) Change the first parameter using the supplied mapper.
default <T> ThrowingBiConsumer<A,T,X>	mapSecond(ThrowingFunction<? super T,? extends B,X> fun) Change the second parameter using the supplied mapper.

Method Detail

accept

void accept(A t,
            B u)
     throws X extends Exception

Performs this operation on the given arguments.

Parameters:

t - the first input argument

u - the second input argument

Throws:

X - if the operation fails

X extends Exception

andThen

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

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

Throws:

NullPointerException - if after is null

curryFirst

default ThrowingConsumer<B,X> curryFirst(A t)

Get a ThrowingConsumer by currying the first parameter.

Parameters:

t - the constant parameter

Returns:

the consumer

currySecond

default ThrowingConsumer<A,X> currySecond(B u)

Get ThrowingConsumer by currying the second parameter.

Parameters:

u - the constant parameter

Returns:

the consumer

mapFirst

default <T> ThrowingBiConsumer<T,B,X> mapFirst(ThrowingFunction<? super T,? extends A,X> fun)

Change the first parameter using the supplied mapper.

Type Parameters:

T - the new type of the first parameter

Parameters:

fun - the mapper

Returns:

the consumer

mapSecond

default <T> ThrowingBiConsumer<A,T,X> mapSecond(ThrowingFunction<? super T,? extends B,X> fun)

Change the second parameter using the supplied mapper.

Type Parameters:

T - the new type of the second parameter

Parameters:

fun - the mapper

Returns:

the consumer
