查询词典 object description

Consequently, the circle viewed as a point still has Circle as a type description because the pointer in its .class com- ponent has not changed. draw is a selector function, i.e., it will take whatever argument is passed as self, proceed to the type description indicated by .class, and call the draw method stored there.

Architecture description languages and their accompanying toolsets have been proposed as the answer. The XYZ/E is an executable linear temporal logic language. It can represent both dynamic and static semantics of systems. Basing on XYZ/E, the executable linar temporal logic language, we provide an architecture description language XYZ/ADL, which can represent both high-level abstract specification and the concrete implementation, thereby provides premise for the smooth transition from specification to implementation. And it can represent both the specification and the inner structure of a component under the unified logic framework, owing to the representability of the XYZ/E.

本项目研究旨在根据XYZ系统的特性，在时序逻辑语言XYZ/E的基础上，提出一种支持在XYZ系统中设计软件体系结构的描述语言XYZ/ADL，使之不仅能够对软件体系结构进行精确的形式化描述，而且为对其进行求精、验证、演化和分析提供基础，从而能在统一的时序逻辑框架下描述组件的规范和它的内部结构，并逐步过渡到最后的算法实现，从而能够支持软件开发设计的逐步求精全过程，把原有的两种支持软件开发的方法即支持模块化程序设计的方法和支持从规范到算法实现的逐步求精的方法有机地结合起来。

In order to improve the expression capability and the performance ofthe graph transformation in applying to software evolution, a softwareevolution operation description language SEOL (Software EvolutionOperation Language) is proposed, and the structured operational semantics on SEOL is studied, and then the semantic equivalence analysismethod about software evolution operation is described.
