  • Constructor Details

    • ObjectNode

      public ObjectNode()

  • Method Details

    • isObject

      public boolean isObject()
      Description copied from interface: JsonNode
      Returns whether this node is an object. 返回此节点是否为对象。
      Specified by:
      isObject in interface JsonNode
      Returns:
      true if object - 如果是对象则返回 true

    • get

      public JsonNode get(String key)
      Description copied from interface: JsonNode
      Gets a child node by property name (for objects). 按属性名获取子节点（用于对象）。
      Specified by:
      get in interface JsonNode
      Parameters:
      key - the property name - 属性名
      Returns:
      the child node, or null - 子节点，或 null

    • has

      public boolean has(String key)
      Description copied from interface: JsonNode
      Returns whether this node has a property (for objects). 返回此节点是否有属性（用于对象）。
      Specified by:
      has in interface JsonNode
      Parameters:
      key - the property name - 属性名
      Returns:
      true if has property - 如果有属性则返回 true

    • keys

      public Set<String> keys()
      Description copied from interface: JsonNode
      Returns the property names (for objects). For JsonNode.ObjectNode the returned set is a live unmodifiable view backed by the node's underlying map: subsequent put / remove on the same JsonNode.ObjectNode are visible through this view, and iterating it while another thread mutates the node will raise ConcurrentModificationException. If you need a stable snapshot or you intend to share the result across threads, copy it: Set.copyOf(node.keys()). Scalar nodes return an empty immutable set. 返回属性名（仅对对象有意义）。JsonNode.ObjectNode 返回的集合是底层 map 的不可变活视图： 后续在同一 JsonNode.ObjectNode 上 put/remove 会通过该视图体现； 在迭代过程中另一线程改动节点会抛 ConcurrentModificationException。 需要稳定快照或跨线程共享时，请用 Set.copyOf(node.keys()) 复制。 标量节点返回空的不可变集合。
      Specified by:
      keys in interface JsonNode
      Returns:
      the property names - 属性名

    • size

      public int size()
      Description copied from interface: JsonNode
      Returns the number of children (for objects/arrays). 返回子元素数量（用于对象/数组）。
      Specified by:
      size in interface JsonNode
      Returns:
      the size - 大小
