  - size
```
public int size()
```
    从类复制的说明: JsonNode
    
    Method that returns number of child nodes this node contains: for Array nodes, number of child elements, for Object nodes, number of fields, and for all other nodes 0.
    
    指定者:
    
    size 在类中 ContainerNode
    
    返回:
    For non-container nodes returns 0; for arrays number of contained elements, and for objects number of fields.

```
public Iterator<JsonNode> getElements()
```
    从类复制的说明: JsonNode
    
    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.

  - get
```
public JsonNode get(int index)
```
    从类复制的说明: JsonNode
    
    Method for accessing value of the specified element of an array node. For other nodes, null is always returned.
    For array nodes, index specifies exact location within array and allows for efficient iteration over child elements (underlying storage is guaranteed to be efficiently indexable, i.e. has random-access to elements). If index is less than 0, or equal-or-greater than node.size(), null is returned; no exception is thrown for any index.
    
    指定者:
    
    get 在类中 ContainerNode

    指定者:
    
    get 在类中 ContainerNode

    This method is similar to JsonNode.get(String), except that instead of returning null if no such value exists (due to this node not being an object, or object not having value for the specified field), a "missing node" (node that returns true for JsonNode.isMissingNode()) will be returned. This allows for convenient and safe chained access via path calls.
