StreamConverters

This object contains methods to create Java Streams that operate on Scala collections (sequentially or in parallel). For more information on Java streams, consult the documentation (https://docs.oracle.com/javase/8/docs/api/java/util/stream/package-summary.html).

The explicit conversion methods defined here are intended to be used in Java code. For Scala code, it is recommended to use the extension methods defined in scala.jdk.StreamConverters.

Note: to convert between Scala collections and classic Java collections, use CollectionConverters.

For details how the stream converters work, see scala.jdk.StreamConverters.

Concrete methods

Create a parallel Java DoubleStream for a Scala collection.

Create a parallel Java DoubleStream for a Scala collection.

Note: parallel processing is only efficient for collections that have a scala.collection.Stepper implementation which supports efficient splitting. For collections where this is the case, the stepper method has a return type marked with EfficientSplit.

Note: this method uses the boxed type java.lang.X instead of the primitive type scala.X to improve compatibility when using it in Java code (the Scala compiler emits C[Int] as C[Object] in bytecode due to scala/bug#4214). In Scala code, add import scala.jdk.StreamConverters._ and use the extension methods instead.
