__NOTOC__ Oxygene (formerly known as Chrome) is a programming language developed by RemObjects Software for Microsoft's Common Language Infrastructure and the Java Platform. Oxygene is Object Pascal-based, but also has influences from C#, Eiffel, Java, F# and other languages. Compared to the now deprecated Delphi.NET, Oxygene does not emphasize total backward compatibility, but is designed to be a "reinvention" of the language, be a good citizen on the managed development platforms, and leverage all the features and technologies provided by the .NET and Java runtimes. Oxygene offers full integration into Visual Studio 2010 and 2012 as a commercial product, and a freely available command line compiler. Starting 2008, RemObjects Software has licensed its compiler and IDE technology to Embarcadero to be used in their Embarcadero Prism product.〔() Embarcadero Prism page, at the bottom of the page an image stating it is powered by RemObjects Oxygene.〕 Starting in the Fall of 2011, Oxygene is available in two separate editions, with the second edition adding support for the Java and Android runtimes. Starting with the release of XE4, Embarcadero Prism is no longer part of the RAD Studio SKU. Numerous support and upgrade paths for Prism customers exist to migrate to Oxygene.〔http://blogs.remobjects.com/blogs/mh/2013/04/17/p5822〕 == The language == The Oxygene language has its origins in Object Pascal in general and Delphi in particular, but was designed to reflect the guidelines of .NET programming and to create fully CLR-compliant assemblies. Therefore, some minor language features known from Object Pascal / Delphi have been dropped or revised, while a slew of new and more modern features, such as Generics or Sequences and Queries have been added to the language. Oxygene is an object-oriented language, which means it uses classes, which can hold data and execute code, to design programs. Classes are "prototypes" for objects, like the idea of an apple is the prototype for the apple one can actually buy in a shop. It is known that an apple has a colour, and that it can be peeled: those are the data and executable "code" for the apple class. Oxygene provides language-level support for some features of parallel programming. The goal is to use all cores or processors of a computer to improve performance. To reach this goal, tasks have to be distributed among several threads. The .NET framework's ThreadPool class offered a way to efficiently work with several threads. The Task Parallel Library (TPL) was introduced in .NET 4.0 to provide more features for parallel programming.Operators can be overloaded in Oxygene using the class operator syntax:Note, that for operator overloading each operator has a name, that has to be used in the operator overloading syntax, because for example "+" would not be a valid method name in Oxygene.〔http://prismwiki.codegear.com/en/Operator_Overloading〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oxygene (programming language)」の詳細全文を読む スポンサード リンク
