本文整理了Java中net.sourceforge.pmd.lang.ast.Node类的一些代码示例，展示了Node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。Node类的具体详情如下：
包路径：net.sourceforge.pmd.lang.ast.Node
类名称：Node

Node介绍

[英]All AST nodes must implement this interface. It provides basic machinery for constructing the parent and child relationships between nodes.
[中]所有AST节点都必须实现此接口。它为构建节点之间的父子关系提供了基本机制。

  1. protected Node getFirstChild(Node contextNode) {
