ContainerNode (jackson-databind 2.4.0-rc1)

java.lang.Object
- com.fasterxml.jackson.databind.JsonNode
- - com.fasterxml.jackson.databind.node.BaseJsonNode
  - - com.fasterxml.jackson.databind.node.ContainerNode<T>

Direct Known Subclasses:

ArrayNode, ObjectNode

  - asToken
```
public abstract com.fasterxml.jackson.core.JsonToken asToken()
```
    Description copied from class: BaseJsonNode
    
    Method that can be used for efficient type detection when using stream abstraction for traversing nodes. Will return the first JsonToken that equivalent stream event would produce (for most nodes there is just one token but for structured/container types multiple)
    
    Specified by:
    
    asToken in interface com.fasterxml.jackson.core.TreeNode
    
    Specified by:
    
    asToken in class BaseJsonNode
  - asText
```
public String asText()
```
    Description copied from class: JsonNode
    
    Method that will return a valid String representation of the container value, if the node is a value node (method JsonNode.isValueNode() returns true), otherwise empty String.
    
    Specified by:
    
    asText in class JsonNode
  - size
```
public abstract int size()
```
    Specified by:
    
    size in interface com.fasterxml.jackson.core.TreeNode
    
    Overrides:
    
    size in class JsonNode
  - get
```
public abstract JsonNode get(int index)
```
    Description copied from class: 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.
    NOTE: if the element value has been explicitly set as null (which is different from removal!), a NullNode will be returned, not null.
    
    Specified by:
    
    get in interface com.fasterxml.jackson.core.TreeNode
    
    Specified by:
    
    get in class JsonNode
    
    Returns:
    Node that represent value of the specified element, if this node is an array and has specified element. Null otherwise.
  - get
```
public abstract JsonNode get(String fieldName)
```
    Description copied from class: JsonNode
    
    Method for accessing value of the specified field of an object node. If this node is not an object (or it does not have a value for specified field name), or if there is no field with such name, null is returned.
    NOTE: if the property value has been explicitly set as null (which is different from removal!), a NullNode will be returned, not null.
    
    Specified by:
    
    get in interface com.fasterxml.jackson.core.TreeNode
    
    Overrides:
    
    get in class JsonNode
    
    Returns:
    Node that represent value of the specified field, if this node is an object and has value for the specified field. Null otherwise.
