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 . |
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 com.fasterxml.jackson.core.JsonToken |
asToken()
Method that can be used for efficient type detection
when using stream abstraction for traversing nodes.

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.

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