scala.util.parsing - Parser combinators (scala-parser-combinators.jar) Automatic imports . Identifiers in the scala package and the scala.Predef object are always in scope by default. Some of these identifiers are type aliases provided as shortcuts to commonly used classes. For example, List is an alias for scala.collection.immutable.List.
Apr 27, 2020 · You want to improve the performance of an algorithm by using Scala’s parallel collections. Solution When creating a collection, use one of the Scala’s parallel collection classes, or convert an existing collection to a parallel collection. In either case, test your algorithm to make sure you see the benefit you’re expecting.
Aug 11, 2016 · Using ParSeq.map is not possible here, since the mapping will be different for every query, and using Future doesn't really seems to fit in this case (I need to use onComplete on each one, see if it failed or not, etc.) Any ideas how to do this simply? scala apache-spark parallel-processing Share Improve this question Follow

Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.
