Method Detail

mergeObject

public static com.fasterxml.jackson.databind.node.ObjectNode mergeObject(com.fasterxml.jackson.databind.node.ObjectNode object1,
                                                                         com.fasterxml.jackson.databind.node.ObjectNode object2)

Safely merge two object nodes. This will place any values from the second node into the first if they do not already exist there. The first object is returned as the merged result.

Throws:

java.lang.IllegalArgumentException - if the merge cannot be completed.

mergeObject

public static com.fasterxml.jackson.databind.node.ObjectNode mergeObject(com.fasterxml.jackson.databind.node.ObjectNode object1,
                                                                         com.fasterxml.jackson.databind.node.ObjectNode object2,
                                                                         boolean throwOnConflict)

mergeArray

public static com.fasterxml.jackson.databind.node.ArrayNode mergeArray(com.fasterxml.jackson.databind.node.ArrayNode array1,
                                                                       com.fasterxml.jackson.databind.node.ArrayNode array2)

Safely merge two array nodes. This will append values from the second array into the first array, and return the first array.

mergeNode

public static com.fasterxml.jackson.databind.JsonNode mergeNode(com.fasterxml.jackson.databind.JsonNode node1,
                                                                com.fasterxml.jackson.databind.JsonNode node2)

Safely merge two nodes. This will appropriately merge objects or lists, as well as verifying that values are compatible if both nodes are values.

mergeNode

public static com.fasterxml.jackson.databind.JsonNode mergeNode(com.fasterxml.jackson.databind.JsonNode node1,
                                                                com.fasterxml.jackson.databind.JsonNode node2,
                                                                boolean throwOnConflict)

Safely merge two nodes. This will appropriately merge objects or lists, as well as verifying that values are compatible if both nodes are values. If throwOnConflict is set, an exception will be thrown if there is a merge conflict. Otherwise, node1 will be returned as the conflict resolution.
