DoubleStream.Builder

public static interface DoubleStream.Builder
implements DoubleConsumer

java.util.stream.DoubleStream.Builder


A mutable builder for a DoubleStream.

A stream builder has a lifecycle, which starts in a building phase, during which elements can be added, and then transitions to a built phase, after which elements may not be added. The built phase begins when the build() method is called, which creates an ordered stream whose elements are the elements that were added to the stream builder, in the order they were added.
