Method Details

processNode

public com.fasterxml.jackson.databind.JsonNode processNode(com.fasterxml.jackson.databind.JsonNode node)
                                                    throws IOException

Throws:

IOException

merge

public static com.fasterxml.jackson.databind.JsonNode merge(com.fasterxml.jackson.databind.JsonNode mainNode,
 com.fasterxml.jackson.databind.JsonNode updateNode)

Merge the given mainNode and updateNode. Merge strategy:

1. Arrays of objects are appended from updateNode to mainNode.
2. Arrays of simple values from updateNode erase the ones in mainNode.
3. updateNode object values overwrite mainNode object values.

Parameters:

mainNode - The main JSON node to merge into.

updateNode - The update JSON node to merge.

Returns:

The merged JSON node.
