摘要
本文提出了二条属性文法的语义局部化原理以及语法分划的新方法,定义了二级属性文法,给出了语义树局部化分解的一种有效算法,建立了二种二级属性计算:狭义二级属性计算和广义二级属性计算。这些结果为属性文法技术更广泛地应用于软件开发找到了更加行之有效的新途径。
This paper presents two principles localizing semantic of attributegrammar and a new method of dividing grammar,defines two-level attribute grammar,gives an effective algorithm of the division localizing semantio tree,builds two kinds oftwo-level attribute evaluation:special two-level attribute evaluation and generalizedtwo-level attribute evaluation.These results are more effective in the wide applicationof attribute grammar technology in software development.
