Builder

interface Builder : LongConsumer

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.

Summary

Public methods
abstract Unit

Adds an element to the stream being built.

open LongStream.Builder!
add(t: Long)

Adds an element to the stream being built.

abstract LongStream!

Builds the stream, transitioning this builder to the built state.

Inherited functions
LongConsumer! andThen(after: LongConsumer!)

Returns a composed LongConsumer that performs, in sequence, this operation followed by the after 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, the after operation will not be performed.
