Method Summary

Modifier and Type	Method and Description

DoubleStream	build() Builds the stream, transitioning this builder to the built state.

Method Detail

accept

void accept(double t)

Adds an element to the stream being built.

A stream builder has a lifecycle, where it 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.

Specified by:

accept in interface DoubleConsumer

Parameters:

t - the input value

Throws:

IllegalStateException - if the builder has already transitioned to the built state

add

default StreamBuilder.OfDouble add(double t)

Adds an element to the stream being built.

Implementation Requirements:

The default implementation behaves as if:

     accept(t)
     return this;
 

Parameters:

t - the element to add

Returns:

this builder

Throws:

IllegalStateException - if the builder has already transitioned to the built state

build

DoubleStream build()

Builds the stream, transitioning this builder to the built state. An IllegalStateException is thrown if there are further attempts to operate on the builder after it has entered the built state.

Returns:

the built stream

Throws:

IllegalStateException - if the builder has already transitioned to the built state
