An overview of BETA
نویسنده
چکیده
BETA is a modern object-oriented language from the Scandinavian school of objectorientation where the first object-oriented language Simula [DMN70] was developed. BETA supports the object-oriented perspective on programming and contains comprehensive facilities for procedural and functional programming. BETA has powerful abstraction mechanisms for supporting identification of objects, classification and composition. BETA is a strongly typed language like Simula, Eiffel [Mey88] and C++ [Str86a], with most type checking being carried out at compiletime. It is well known that it is not possible to obtain all type checking at compile time without sacrificing the expressiveness of the language. BETA has an optimum balance between compile-time type checking and run-time type checking. The purpose of this chapter is to present an overview of the BETA language and give examples on the use of most constructs. The reader is assumed to be familiar with one or more object-oriented languages like Simula, Eiffel, C++, or Smalltalk [GR83]. For more details about BETA see [KMM+83b,KKM+87b,MMN93].
