Finds a given path (element in the json). Recursion.

Parameters:

currentJson - current json element

completeExpression - complete expression, used to build exception message

traversalPath - current traversal path

allowMissingNode - if true does not throw exception if node was not found

Converts a Json into a HashMap with the results

Parameters:

json - json node to be flattened

Returns:

LinkedHashMap<String, JsonNode> elements found
