本文整理了Java中org.antlr.v4.runtime.Parser.getCurrentToken()方法的一些代码示例，展示了Parser.getCurrentToken()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.getCurrentToken()方法的具体详情如下：
包路径：org.antlr.v4.runtime.Parser
类名称：Parser
方法名：getCurrentToken

Parser.getCurrentToken介绍

[英]Match needs to return the current input symbol, which gets put into the label for the associated token ref; e.g., x=ID.
[中]Match需要返回当前输入符号，该符号被放入相关令牌ref的标签中；e、 g.，x=ID。

currentToken = parser.getCurrentToken();

  if (currentToken != null) {
    int line = currentToken.getLine();
    int column = currentToken.getCharPositionInLine();
    offendingToken = currentToken.getText();
    sourcePreview = mkPreview(line);
    sourceLocation = new SourceLocation(line, column, sourceName);
  }
  return new InvalidSyntaxException(sourceLocation, null, sourcePreview, offendingToken, cause);
