Interface Consumer<T>

Type Parameters:
T - the type of the input to the operation
All Known Subinterfaces:
ClassBuilder,ClassFileBuilder<E,B>,CodeBuilder,CodeBuilder.BlockCodeBuilder,FieldBuilder,MethodBuilder,Stream.Builder<T>
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterfacepublic interfaceConsumer<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 afunctional interface whose functional method isaccept(Object).

  • Method Details

    • accept

      void accept(T t)
      Performs this operation on the given argument.
      Parameters:
      t - the input argument

    • andThen

      default Consumer<T> andThen(Consumer<? superT> after)
      Returns a composedConsumer that performs, in sequence, this operation followed by theafter 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, theafter operation will not be performed.
      Parameters:
      after - the operation to perform after this operation
      Returns:
      a composedConsumer that performs in sequence this operation followed by theafter operation
      Throws:
      NullPointerException - ifafter is null
