We will keep a reference to the Object (usually TreeMapper)
that can construct instances of nodes to add to this container
node.

Modifier and Type | Method and Description |

ArrayNode |
arrayNode()
Factory method that constructs and returns an empty
ArrayNode
Construction is done using registered JsonNodeFactory . |
ArrayNode |
arrayNode(int capacity)
Factory method that constructs and returns an
ArrayNode with an initial capacity
Construction is done using registered JsonNodeFactory |
String |
asText()
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. |
abstract JsonToken |
asToken()
Method that can be used for efficient type detection
when using stream abstraction for traversing nodes.

binaryNode(byte[] data,
int offset,

BooleanNode |
booleanNode(boolean v) |
abstract JsonNode |
get(int index)
Method for accessing value of the specified element of
an array node.
|
abstract JsonNode |
get(String fieldName)
Method for accessing value of the specified field of
an object node.

rawValueNode(RawValue value)
Factory method to use for adding "raw values"; pre-encoded values
that are included exactly as-is when node is serialized.
|
abstract T |
removeAll()
Method for removing all children container has (if any)
|
abstract int |
size()
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.

public abstract JsonNode get(int index)
JsonNode
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.

NOTE: if the property value has been explicitly set as null
(which is different from removal!),
a NullNode
will be returned,
not null.
