DoubleStream.Builder
implements
DoubleConsumer
| java.util.stream.DoubleStream.Builder
|
A mutable builder for a DoubleStream.
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.
Summary
Public methods |
|---|
abstract
void
|
accept(double t)
Adds an element to the stream being built.
|
default
DoubleStream.Builder
|
add(double t)
Adds an element to the stream being built.
|
abstract
DoubleStream
|
build()
Builds the stream, transitioning this builder to the built state.
|
Public methods
accept
public abstract void accept (double t)
Adds an element to the stream being built.
| Parameters |
|---|
t |
double: the input argument |
add
public DoubleStream.Builder 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 |
double: the element to add |
build
public abstract 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.
