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兩個語法樹,那么該句子是二義性的。
A parse of a sentential form is the construction of a derivation and possibly a syntax tree for it . 句型的分析是某個推導(dǎo)(或許是其語法樹)的構(gòu)造過程。
If a sentential form is ambiguous, then it has more than one syntax tree and therefore, in general, more than one handle . 如果句型是二義性的,那末,它不只有一棵語法樹,因此,一般地說,也不只有一個句柄。
Generating abstract syntax trees 生成抽象語法樹
A parse of a sentential form is the construction of a derivation and possibly a syntax tree for it 句型的分析是某個推導(dǎo)(或許是其語法樹)的構(gòu)造過程。
Traverses the abstract syntax tree one or more times , collecting information and checking that the input program 遍歷抽象語法樹( abstract syntax tree , ast )一次或多次,收集信息并檢查輸入程序
This paper introduced a kind of variable type collecting method , which is based on layered thoughtway and abstract syntax tree 摘要提出了一種基于分層思想的,并且無需構(gòu)造具體語法樹的變量類型提取方法。
An abstract syntax tree is built after syntax analysis and traversed three times to do semantic analysis to generate the intermediate code 在語法分析、語義分析及中間代碼生成方面,先經(jīng)過語法分析建立抽象語法樹,然后對抽象語法樹進(jìn)行三次遍歷完成語義分析并生成中間代碼。
Start generating depth - first visitors automatically with the java tree builder , a syntax tree builder used with the java compiler compiler javacc parser generator 開始自動生成深度優(yōu)先訪問器, java樹構(gòu)建器它是一種與java compiler compiler ( javacc )解析生成器一起使用的語法樹構(gòu)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 您可以添加新規(guī)則:可以通過編寫java代碼并重新編譯pdm ,或者更簡單些,編寫xpath表達(dá)式,它會針對每個java類的抽象語法樹進(jìn)行處理。
