Converts a generic Java Stream wrapping a primitive type to a corresponding primitive Stream.
Converts a generic Java Stream wrapping a primitive type to a corresponding primitive Stream.
Type parameters
- S
-
the resulting primitive stream type (e.g.,
IntStream,LongStream,DoubleStream)
Value parameters
- unboxer
-
implicit conversion from boxed
Stream[A]to primitive streamS
Attributes
- Returns
-
a primitive Java Stream of type
Scontaining the unboxed elements of this stream - Source

Copies the elements of this stream into a Scala collection.
Copies the elements of this stream into a Scala collection.
Converting a parallel streams to an scala.jdk.Accumulator using stream.toScala(Accumulator) builds the result in parallel.
A toScala(Accumulator) call automatically converts streams of boxed integers, longs or doubles are converted to the primitive accumulators (scala.jdk.IntAccumulator, etc.).
When converting a parallel stream to a different Scala collection, the stream is first converted into an scala.jdk.Accumulator, which supports parallel building. The accumulator is then converted to the target collection. Note that the stream is processed eagerly while building the accumulator, even if the target collection is lazy.
Sequential streams are directly converted to the target collection. If the target collection is lazy, the conversion is lazy as well.
Type parameters
- C1
-
the type of the target Scala collection
Value parameters
- factory
-
the factory used to build the target collection
- info
-
implicit evidence connecting the element type to a specialized
Accumulator, or a generic fallback (resolved automatically)
Attributes
- Returns
-
the elements of this stream collected into a Scala collection of type
