Interface IntConsumer

All Known Subinterfaces:

IntStream.Builder

All Known Implementing Classes:

IntSummaryStatistics, LongSummaryStatistics

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 IntConsumer

Represents an operation that accepts a single int-valued argument and returns no result. This is the primitive type specialization of Consumer for int. Unlike most other functional interfaces, IntConsumer is expected to operate via side-effects.

This is a functional interface whose functional method is accept(int).

Since:

1.8

Method Summary

Modifier and Type	Method	Description
void	accept(int value)	Performs this operation on the given argument.
default IntConsumer	andThen(IntConsumer after)	Returns a composed IntConsumer that performs, in sequence, this operation followed by the after operation.

Method Details

accept

void accept(int value)

Performs this operation on the given argument.

Parameters:

value - the input argument

andThen

default IntConsumer andThen(IntConsumer after)

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

Throws:

NullPointerException - if after is null
