So scala 2.9 recen开发者_运维百科tly turned up in Debian testing, bringing the newfangled parallel collections with it.
There\'s something I don\'t understand about Scala\'s collection.mutable.Seq. It describes the 开发者_JAVA百科interface for all mutable sequences, yet I don\'t see methods to append or prepend element
I have java API which return this type: ArrayList[ArrayList[String]] = Foo.someJavaMethod() In scala program, I need to send above type as a开发者_Go百科 parameter to a scala function \'bar\' whose
If I have a new collection with an additional attribute, e.g. : class NewColl(var name: String, var values: Vector[Int])
I recently stumbled over this post, which \"introduces\" the collect method for Scala collections. The usage is straight forward:
There are a lot of common concepts: immutable collection, collection view, strict/non strict collection,
开发者_Go百科I\'m having some trouble with this code. It\'s supposed to be an OperationTree with Elements BinaryOperations and UnaryOperations.
I\'m puzzled as to how to solve this in Scala. In Java I\'d give up on generics or use casts, but Scala is more strict than that. Here\'s what I have.
Scala 2.9 introduced parallel collections. They are a really great tool for certain tasks. However, how do they work internally and am I able to influence the behavior/configuration?
I am trying to work more with scalas immutable collection since this is easy to parallelize, but i struggle with some newbie problems. I am looking for a way to create (efficiently) a new Vector from
