EclipseJFaceText框架中IDocument接口的getNumberOfLines方法详解与编程实例

本文整理了Java中org.eclipse.jface.text.IDocument.getNumberOfLines()方法的一些代码示例，展示了IDocument.getNumberOfLines()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。IDocument.getNumberOfLines()方法的具体详情如下：
包路径：org.eclipse.jface.text.IDocument
类名称：IDocument
方法名：getNumberOfLines

IDocument.getNumberOfLines介绍

[英]Returns the number of lines in this document.

Note that a document always has at least one line.
[中]返回此文档中的行数。
请注意，文档始终至少有一行。
