本文整理了Java中com.fasterxml.jackson.databind.JsonNode.isPojo()方法的一些代码示例，展示了JsonNode.isPojo()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。JsonNode.isPojo()方法的具体详情如下：
包路径：com.fasterxml.jackson.databind.JsonNode
类名称：JsonNode
方法名：isPojo

JsonNode.isPojo介绍

[英]Method that can be used to check if the node is a wrapper for a POJO ("Plain Old Java Object" aka "bean". Returns true only for instances of POJONode.
[中]方法，该方法可用于检查节点是否是POJO的包装（“纯旧Java对象”又名“bean”）。仅对POJONode的实例返回true。

代码示例

@Override

    JsonNode n = currentNode();
    if (n != null) {
      if (n.isPojo()) {
        return ((POJONode) n).getPojo();

      if (n.isBinary()) {
        return ((BinaryNode) n).binaryValue();
      }
    }
  }
  return null;
