Examples of com.fasterxml.jackson.databind.ObjectMapper.readTree()

com.fasterxml.jackson.databind.ObjectMapper.readTree()
Method to deserialize JSON content as tree expressed using set of {@link JsonNode} instances. Returnsroot of the resulting tree (where root can consist of just a single node if the current event is a value event, not container).
