DoubleStream.Builder

public static interface DoubleStream.Builder
implements DoubleConsumer

java.util.stream.DoubleStream.Builder

DoubleStream可变建设者。

流生成器具有生命周期，该生命周期始于构建阶段，在此阶段中可以添加元素，然后过渡到构建阶段，之后可能不会添加元素。 构建阶段在调用build()方法时开始，该方法创建一个有序流，其元素是按照添加顺序添加到流构建器的元素。

也可以看看：

Summary

Public methods
abstract void accept(double t)

为正在构建的流添加一个元素。
default DoubleStream.Builder add(double t)

为正在构建的流添加一个元素。
abstract DoubleStream build()

构建流，将此构建器转换为构建状态。

Inherited methods
From interface java.util.function.DoubleConsumer

Public methods

accept

Added in API level 24 
void accept (double t)

为正在构建的流添加一个元素。

Parameters
t double: the input argument
Throws
IllegalStateException if the builder has already transitioned to the built state

add

Added in API level 24 
DoubleStream.Builder add (double t)

为正在构建的流添加一个元素。

实现要求：
  • The default implementation behaves as if: 
    accept(t)
     return this;
Parameters
t double: the element to add
Returns
DoubleStream.Builder this builder
Throws
IllegalStateException if the builder has already transitioned to the built state

build

Added in API level 24 
DoubleStream build ()

构建流，将此构建器转换为构建状态。 如果在构建器进入构建状态后还有更多尝试在构建器上进行操作，则会抛出IllegalStateException 。

Returns
DoubleStream the built stream
Throws
IllegalStateException if the builder has already transitioned to the built state
