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

JsonNodeFactory介绍

[英]Base class that specifies methods for getting access to Node instances (newly constructed, or shared, depending on type), as well as basic implementation of the methods. Designed to be sub-classed if extended functionality (additions to behavior of node types, mostly) is needed.
[中]指定访问节点实例（新构造的或共享的，取决于类型）的方法以及这些方法的基本实现的基类。如果需要扩展功能（主要是增加节点类型的行为），则设计为子类。
