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

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