Class ObjectNode

java.lang.Object

com.fasterxml.jackson.databind.JsonNode

com.fasterxml.jackson.databind.node.BaseJsonNode

com.fasterxml.jackson.databind.node.ContainerNode<ObjectNode>

com.fasterxml.jackson.databind.node.ObjectNode

All Implemented Interfaces:

TreeNode, JsonSerializable, Iterable<JsonNode>

public final class ObjectNode
extends ContainerNode<ObjectNode>

Override of Jackson's ObjectNode

We override it to make it final (the original implementation isn't), which also allows for code simplification all around.

Parameters:

value - to set field to; if null, will be converted to a NullNode first (to remove field entry, call remove(java.lang.String) instead)

NOTE: this method will be deprecated in 2.2; and should be replace with either set(String, JsonNode) or replace(String, JsonNode), depending on which return value is desired for possible chaining.
