A lot of developers have already come up with very cool applications for them. The Scala 2.9.0 codebase includes the following new features and changes: Every collection may be converted into a corresponding parallel collection with the new trait were almost as convenient to write, but were not thread-safe and were often not optimized by the VM, since the application’s body was execited as part of of the object’s initialization sequence.Objects inheriting the trait provides another tool to customize initialization sequences of classes and objects.The previous compiler magic has been replaced by a more systematic and predictable implementation in terms of implicit conversions. Scala 2.8 adds specialized type parameters, which enable the compiler to generate transparently multiple versions of a given definition, and to use the most specific version whenever the static type information at a call site allows it. Named arguments improve the readability of method calls with many arguments.
I like to think of the Visual Library more generally, however, as an API for creating interactive “whiteboards” where you can place, move, and rearrange items visually.It is a kind of container for components, which occupies the rectangular piece on the screen and shows the components arranged in some simple way.How exactly the components are arranged depends on which layout have you set to that panel.Improved programmability: the repl classloader exposes repl-defined classes via their given names.Scala code can now be executed in any of the following ways: , which allows for more efficient array indexing and updates. Scala 2.8.0 is a significantly innovative release, which contains a large amount of fixes and introduces many new features: The collection library has undergone a complete overhaul for Scala 2.8, offering a more coherent and efficient design, while maintaining virtually complete compatibility with existing sources. Handling of arrays has been simplified and optimized in Scala 2.8.
