本文整理了Java中org.antlr.v4.runtime.Parser.getATN()方法的一些代码示例，展示了Parser.getATN()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Parser.getATN()方法的具体详情如下：
包路径：org.antlr.v4.runtime.Parser
类名称：Parser
方法名：getATN

Parser.getATN介绍

[英]The ATN with bypass alternatives is expensive to create so we create it lazily.
[中]带有旁路替代方案的ATN创建成本很高，所以我们懒散地创建它。

代码示例

代码示例来源：origin: prestodb/presto

  1. Parser parser = (Parser) recognizer;
  2. ATN atn = parser.getATN();

代码示例来源：origin: apache/incubator-shardingsphere

  1. Token token = tokens.LT(1);
  2. ATNState state = recognizer.getInterpreter().atn.states.get(recognizer.getState());
  3. IntervalSet nextTokens = recognizer.getATN().nextTokens(state);
  4. if (nextTokens.contains(token.getType())) {
  5.   nextTokensContext = null;
