本文整理了Java中org.antlr.runtime.Parser类的一些代码示例，展示了Parser类的具体用法。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类的具体详情如下：
包路径：org.antlr.runtime.Parser
类名称：Parser

Parser介绍

[英]A parser for TokenStreams. "parser grammars" result in a subclass of this.
[中]令牌流的解析器。“语法分析器”产生了这个类的一个子类。

代码示例

代码示例来源：origin: JesusFreke/smali

public String getErrorMessage(RecognitionException e,

  if (e instanceof NoViableAltException) {
   NoViableAltException nvae = (NoViableAltException)e;
   msg = " no viable alt; token="+getTokenErrorDisplay(e.token)+
   " (decision="+nvae.decisionNumber+
   " state "+nvae.stateNumber+")"+
   " decision=<<"+nvae.grammarDecisionDescription+">>";
  } else {

  }
  return stack + " " + msg;
 } else {
  return super.getErrorMessage(e, tokenNames);
 }
}
