摘要

Ion生成隐藏细节的模型，提取被建模对象的本质，以及块概念。多层抽象有助于表示和管理不同数量的T(x) => P(x)持有，其中T是对象n的类型，如果它持有，则意味着某些属性P对于x是真的。属性P通常只是签名，而不是完整的语义。鉴于上述类和类型的谓词，我们可以如下定义类和类型的泛化/专门化:

Understanding object-model concepts

ion produces models that hide detail, extract the essence of objects being modeled, and chunk concepts. Multiple levels of abstraction facilitate the presentation and management of varying amounts of T(x) => P(x) holds, where T is a type for an object n, which, if it holds, implies that certain properties P are true for X. The properties P are usually only signatures, not full semantics. Addendum to the Proceedings OOPSLA’93 137 Generalization/Specialization Given the predicates above for class and type, we can define generalization/specialization for classes and types as follows:
