IntConsumer

  • IntConsumer represents an operation that accepts a single integer and returns no result, primarily designed for side-effects.

  • It is a functional interface with a primary method accept(int) to perform the operation on the given integer.

  • IntConsumer provides the andThen method to combine operations sequentially, enabling chaining of actions.

  • Subclasses like IntStream.Builder and IntSummaryStatistics utilize IntConsumer for building streams or collecting statistics.
public interface IntConsumer
Known Indirect Subclasses

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).

Public Method Summary

abstract void
accept(int value)
Performs this operation on the given argument.
IntConsumer
andThen(IntConsumer after)
Returns a composed IntConsumer that performs, in sequence, this operation followed by the after operation.

Public Methods

public abstract void accept (int value)

Performs this operation on the given argument.

Parameters
value the input argument

public 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
