LongStream.Builder
implements
LongConsumer
| java.util.stream.LongStream.Builder |
A mutable builder for a LongStream.
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
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.
