摘要
本文依据复杂对象的内部状态,用标识文法表示其结构,将形式语言的概念和对象层次结构联系起来;阐述复杂对象权的概念以及对象和标识文法之间的等价关系,讨论了关于对象演算的并行处理,给出了在特定并行环境下,顺序执行与并行执行的复杂性;在构造对象公式和相关文法形式模型的基础上,研究了非常复杂对象(如对象数据库)的操作和准则。
We built an identifier formal grammar to represent structure of a complex object in terms ofits internal state, intending to join conceptions of formal language and object hierarchy structure.Concepts of weight of a complex object, equivalence between objects and their identifier grammarsare presented. Parallel processing for some calculus of objects and associated operations about thegrammars are also considered.
