Method Details

getJsonObject

public JsonText.JsonObjectResult getJsonObject(String jsonString)

Parses a JSON string and returns a JsonText.JsonObjectResult indicating the outcome.

This method attempts to parse the provided JSON string into a Map. If the JSON string contains a key named $class, it tries to instantiate an object of that class using the parsed JSON map and the original JSON string. The result of the parsing and potential instantiation is encapsulated in a JsonText.JsonObjectResult object.

Possible results include:

• JsonText.JsonObjectResult.ValidResult - The JSON was parsed successfully and an instance of the specified class was created.
• JsonText.JsonObjectResult.ValidResultClassNotFound - The JSON was parsed successfully, but the specified class was not found.
• JsonText.JsonObjectResult.ValidResultClassNotInstantiated - The JSON was parsed successfully, but the specified class could not be instantiated.
• JsonText.JsonObjectResult.ValidUntypedResult - The JSON was parsed successfully but does not specify a class.
• JsonText.JsonObjectResult.InvalidResult - The JSON could not be parsed or other errors occurred.

Usage example:

 
 String jsonString = "{\"$class\":\"com.example.MyClass\", \"key\":\"value\"}";
 JsonObjectResult result = myObject.getJsonObject(jsonString);

 if (result instanceof JsonObjectResult.ValidResult) {
     // handle valid result
 } else if (result instanceof JsonObjectResult.InvalidResult) {
     // handle invalid result
 }
 
 

Parameters:

jsonString - the JSON string to parse

Returns:

a JsonText.JsonObjectResult object representing the outcome of the parsing and potential instantiation
