ANTLR 接受3类语法规范——语法分析程序，词法分析程序lexers，和树语法分析程序(也

叫树行者)。 由ANTLR使用LL(k) 分析用于全部3 语法变型，由于语法说明相似，因而产生

的lexers 和语法分析程序表现得也类似。 产生的识别程序易读，你可以查看输出的内容来

消除很多关于ANTLR机理的问题。-ANTLR grammar to accept 3 types of norms- syntax analysis procedures, lexical analysis program lexers, and tree parser (also known as tree Departed). ANTLR use by the LL (k) Analysis of syntax used for all 3 variants, as the syntax that is similar to the resultant lexers and syntax analysis program was also similar. Identification procedures have read, you can view the contents of the output to eliminate a lot about the mechanism of ANTLR issue.
