Interface DoubleConsumer

All Known Subinterfaces:
DoubleStream.Builder
All Known Implementing Classes:
DoubleSummaryStatistics
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterfacepublic interfaceDoubleConsumer
Represents an operation that accepts a singledouble-valued argument and returns no result. This is the primitive type specialization ofConsumer fordouble. Unlike most other functional interfaces,DoubleConsumer is expected to operate via side-effects.

This is afunctional interface whose functional method isaccept(double).

    Description
    void
    accept(double value)
    Performs this operation on the given argument.
    Returns a composedDoubleConsumer that performs, in sequence, this operation followed by theafter operation.

  • Method Details

    • accept

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

    • andThen

      default DoubleConsumer andThen(DoubleConsumer after)
      Returns a composedDoubleConsumer 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 composedDoubleConsumer that performs in sequence this operation followed by theafter operation
      Throws:
      NullPointerException - ifafter is null
