A sentence of a grammar is ambiguous if there exists two syntax trees for it . 如果一文法的句子存在两个语法树,那么该句子是二义性的。
A parse of a sentential form is the construction of a derivation and possibly a syntax tree for it . 句型的分析是某个推导(或许是其语法树)的构造过程。
If a sentential form is ambiguous, then it has more than one syntax tree and therefore, in general, more than one handle . 如果句型是二义性的,那末,它不只有一棵语法树,因此,一般地说,也不只有一个句柄。
Generating abstract syntax trees 生成抽象语法树
A parse of a sentential form is the construction of a derivation and possibly a syntax tree for it 句型的分析是某个推导(或许是其语法树)的构造过程。
Traverses the abstract syntax tree one or more times , collecting information and checking that the input program 遍历抽象语法树( abstract syntax tree , ast )一次或多次,收集信息并检查输入程序
This paper introduced a kind of variable type collecting method , which is based on layered thoughtway and abstract syntax tree 摘要提出了一种基于分层思想的,并且无需构造具体语法树的变量类型提取方法。
An abstract syntax tree is built after syntax analysis and traversed three times to do semantic analysis to generate the intermediate code 在语法分析、语义分析及中间代码生成方面,先经过语法分析建立抽象语法树,然后对抽象语法树进行三次遍历完成语义分析并生成中间代码。
Start generating depth - first visitors automatically with the java tree builder , a syntax tree builder used with the java compiler compiler javacc parser generator 开始自动生成深度优先访问器, java树构建器它是一种与java compiler compiler ( javacc )解析生成器一起使用的语法树构建器。
You can add new rules , either by writing java code and recompiling pmd or , a little more simply , by writing xpath expressions that are resolved against each java class s abstract syntax tree 您可以添加新规则:可以通过编写java代码并重新编译pdm ,或者更简单些,编写xpath表达式,它会针对每个java类的抽象语法树进行处理。
