Class ModelTypeProcessor

java.lang.Object

io.adminshell.aas.v3.dataformat.json.modeltype.ModelTypeProcessor

public class ModelTypeProcessor
extends Object

Helper class to deal with nested nature of modelType property in JSON. As Jackson can not natively deal with such nested type information, this class offers functions to unwrapp the modelType information via the preprocess(...) method and wrap it again via postprocess(...).

Method Detail

preprocess

public static com.fasterxml.jackson.databind.JsonNode preprocess(String json)
                                                          throws com.fasterxml.jackson.core.JsonProcessingException

 "modelType": {
      "name": "Foo"
 }
 

to

 "modelType": "Foo"
 

Parameters:

json - json as string

Returns:

root node with unwrapped type information

Throws:

com.fasterxml.jackson.core.JsonProcessingException - parsing JSON fails

postprocess

public static com.fasterxml.jackson.databind.JsonNode postprocess(com.fasterxml.jackson.databind.JsonNode node)
                                                           throws com.fasterxml.jackson.core.JsonProcessingException

Wraps type information recursively, e.g. converts

 "modelType": "Foo"
 

to

 "modelType": {
      "name": "Foo"
 }
 

Parameters:

node - root node

Returns:

transformed root node

Throws:

com.fasterxml.jackson.core.JsonProcessingException - parsing JSON fails
