本文整理了Java中org.openide.text.Line类的一些代码示例，展示了Line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。Line类的具体详情如下：
包路径：org.openide.text.Line
类名称：Line

Line介绍

[英]Represents one line in a text document. The line number may change when the text is modified, but the identity of the line is retained. It is designed to allow line-dependent modules of the IDE (such as the compiler and debugger) to make use of a line consistently even as the text is modified.
[中]表示文本文档中的一行。修改文本时，行号可能会更改，但行的标识将保留。它的设计允许IDE的行相关模块（如编译器和调试器）在修改文本时一致地使用行。

        if (lineNum == -1) {
          // OK, just open it.
          ed.open();
        } else {
          ed.openDocument();//XXX getLineSet doesn't do it for you
          try {
            Line l = ed.getLineSet().getOriginal(lineNum - 1);
            if (!l.isDeleted()) {
