public static interface DoubleStream.Builder extends DoubleConsumer
A mutable builder for aDoubleStream.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.- Since:
