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

JsonNode.getElements介绍

[英]Method for accessing all value nodes of this Node, iff this node is a JSON Array or Object node. In case of Object node, field names (keys) are not included, only values. For other types of nodes, returns empty iterator.
[中]方法访问此节点的所有值节点，如果此节点是JSON数组或对象节点。对于对象节点，不包括字段名（键），仅包括值。对于其他类型的节点，返回空迭代器。

public Array(JsonNode n, NodeCursor p) {
  super(JsonStreamContext.TYPE_ARRAY, p);
  _contents = n.getElements();
}

/**
 * Same as calling {@link #getElements}; implemented so that
 * convenience "for-each" loop can be used for looping over elements
 * of JSON Array constructs.
 */
@Override
public final Iterator<JsonNode> iterator() { return getElements(); }

       UUID_FIELD)).findFirst().isPresent();

  case ARRAY:
