Interface Consumer<T>

Type Parameters:
T - the type of the input to the operation
All Superinterfaces:
Consumer<T>
All Known Subinterfaces:
DoubleConsumer, IntConsumer, LongConsumer
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 Consumer<T>
extends Consumer<T>
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.

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

  • Method Summary

    Modifier and Type Method Description
    void accept​(T t)
    Performs this operation on the given argument.
    default Consumer<T> andThen​(Consumer<? super T> after)
    Returns a composed Consumer that performs, in sequence, this operation followed by the after operation.
    default Runnable applyPartial​(T t)
    Partially apply a parameter such that a single param consumer becomes a no-param runnable.

  • Method Details

    • accept

      void accept​(T t)
      Performs this operation on the given argument.
      Specified by:
      accept in interface Consumer<T>
      Parameters:
      t - the input argument

    • andThen

      default Consumer<T> andThen​(Consumer<? super T> 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

    • applyPartial

      default Runnable applyPartial​(T t)
      Partially apply a parameter such that a single param consumer becomes a no-param runnable.
      Parameters:
      t - The parameter to apply.
      Returns:
      A partially-applied function.
