抽象語法樹 的英文怎麼說
中文拼音 [chōuxiàngyǔfǎshù]
抽象語法樹
英文
abstract syntax tree-
The gcc compiler scales very well - from simple batch utility programs to multimillion - line systems. it is the clear syntax tree front end, the highly recapitulative intermediate language and the concise machine description back end that help gcc port to kinds of platforms
其清晰的前端語法樹結構、高度概括的抽象機中間語言、簡潔有力的後端機器描述等三部分為快速實現多語種開發、多平臺移植提供了有力的支持。C c abstract syntax in software instant test
抽象語法樹的生成Generating abstract syntax trees
生成抽象語法樹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，收集信息並檢查輸入程序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，先經過語法分析建立抽象語法樹，然後對抽象語法樹進行三次遍歷完成語義分析並生成中間代碼。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
您可以添加新規則：可以通過編寫java代碼並重新編譯pdm ，或者更簡單些，編寫xpath表達式，它會針對每個java類的抽象語法樹進行處理。You would never use a scanner to analyze an entire java source ; for that you would turn to something quite familiar to compiler aficionados : the jdt s abstract syntax tree framework
您決不會使用掃描程序分析整個java源代碼；因為您會轉而使用一些對編譯器迷而言十分熟悉的工具： jdt的抽象語法樹（ abstract syntax tree ， ast ）框架。Existent automatic grading model of programs can not deal with the programs with structural body. in this paper, we study the syntax and concept of structural body based on an existed model, and improve the original model in the following aspects : increasing the middle representation form of structural body in analysis of morphology and syntax and system dependence graph and abstract syntax tree, adding standardization rules, mainly including type definition, nesting structure, initialization, function invocation, renaming and sequence of program sentence, besides standardization rules of bit operation and program with enumeration, enhancing the function of inspecting syntax error and improving matching strategies
本文在原有的編程題自動評分模型的基礎上，對結構體的語法結構和實現原理進行研究，並在以下幾個方面完善原有模型:在詞法和語法分析、程序的系統依賴圖建立和抽象語法樹生成三個方面增加結構體類型的中間表示形式;擴充程序的標準化規則，主要包括類型定義標準化、結構體嵌套結構標準化、結構體初始化的標準化、結構體作為函數參數時函數調用標準化、結構體變量名稱標準化、結構體語句排列順序標準化等等;另外，還增加了位運算標準化、枚舉標準化以及文件的處理;增強學生程序中語法錯誤的檢測和改進程序匹配策略。The following works have been done : ( 1 ) define csl language and complete the lexical analysis and syntactical analysis of it ; ( 2 ) obtain control flow graph ( later referred as cfg ) from abstract syntax tree ( ast ) ; ( 3 ) control dependence analysis of csl ; ( 4 ) system architecture of csl slicing system
內容包括通過語法分析獲得源程序的抽象語法樹，從抽象語法樹構造控制流圖，在控制流圖上做控制流分析獲得源程序的控制依賴關系，在控制流圖上做數據流分析獲得源程序的數據依賴關系，以及最後獲得源程序的程序依賴圖並以圖可達性演算法獲得程序分片的全過程。This dissertation systematically generalizes theory, methods and techniques of software metrics, depicts an inproved software quality metrics model and brings forward a new software metrics tool architecture that based on abstract syntax tree. a software metrics tools named emmetrics is designed and implemented based on the new architecture, so metrics data can be automatically collected, analyzed and exhibited
本文系統歸納了軟體度量的理論、方法和技術，改進了已有的軟體質量度量模型，提出了一種以抽象語法樹為核心的度量工具的體系結構，並且基於該體系結構設計並實現了一個自動化軟體度量工具emmetrics ，實現了度量數據的自動採集、分析與展示。Different from other researches, autoore uses the proposed java semantic model as input data, and gives a tree - liked, hierarchical structured and semantic cluster set. the clustering method is based on a minimum spanning tree that represents the software system. the clustering objective function is designed according to the software modularization metric and cognition psychology theory
抽象是autoore的核心，它首次採用對象系統的語義關系抽取數據為輸入，利用基於mst表示的、聚集目標結合了程序認知心理學理論的軟體聚集方法，得到一個具有豐富語義的、組織為樹狀的、分層的聚集集合。分享友人
