                                                                    String fieldName)

Returns the field from a ObjectNode as ObjectNode

getObjAndRemove

public static com.fasterxml.jackson.databind.node.ObjectNode getObjAndRemove(com.fasterxml.jackson.databind.node.ObjectNode obj,
                                                                             String fieldName)

Removes the field from a ObjectNode and returns it as ObjectNode

createArray

public static com.fasterxml.jackson.databind.node.ArrayNode createArray(com.fasterxml.jackson.databind.JsonNode... nodes)
