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

Tree.isNil介绍

[英]Indicates the node is a nil node but may still have children, meaning the tree is a flat list.
[中]指示该节点为nil节点，但可能仍有子节点，这意味着该树是一个平面列表。

代码示例

代码示例来源：origin: apache/hive

Tree otherP = otherStack.pop();
if (p.isNil() != otherP.isNil()) {
 return false;
if (!p.isNil()) {
 if (!p.toString().equals(otherP.toString())) {
  return false;

Tree otherP = otherStack.pop();
if (p.isNil() != otherP.isNil()) {
 return false;
if (!p.isNil()) {
 if (!p.toString().equals(otherP.toString())) {
  return false;
