看这个图片里面的例子,我们可以看到这个左下的code被parse成了一颗abstractsyntax tree(AST)。在生成训练数据的时候,由于我们已经有了grammar和python code。code to AST的过程是一个bottom-up的过程,code里面的每一个token会被当成叶子节点,然后会被分到它属于的类,然后这个类别也会属于另外一个层级的类别,到最后会...
AST abstract syntax tree (抽象语法结构树),是对java语言的一种抽象,每个节点都能对应到一种java语法,最终一个java文件就是由一棵节点树构成。 package com.sun.tools.javac.tree;回到目录 AST 节点类型com.sun.source.tree.Tree.Kind枚举类型Tree节点类型定义示例 ANNOTATED_TYPE AnnotatedTypeTree 注解类型,可以...
In computer science, an abstract syntax tree (AST), or just syntax tree, is a tree representation of the abstract syntactic structure of source code written in a programming language. 翻译为: 在计算机科学中,抽象语法树(abstract syntax tree或者缩写为AST),或者语法树(syntax tree),是源代码的抽象语...

If an IR is used as an abstract syntax tree for representing an IDL specification, modules M1 and M2 are both represented by an object within the IR. If during code generation the back end passes through the content of the IR sequentially this would produce the following sequence of IDL ...
