Classes

  Type Name Description
Public struct FJsonDataBag Useful if you just want access to the underlying FJsonObject (for cases where the schema is loose or an outer system will do further de/serialization)  
Public struct FJsonSerializable Base class for a JSON serializable object  
Public class FJsonSerializer    
Public struct FJsonSerializerBase Base interface used to serialize to/from JSON. Hides the fact there are separate read/write classes  
Public class FJsonSerializerReader Implements the abstract serializer interface hiding the underlying reader object  
Public class FJsonSerializerWriter Implements the abstract serializer interface hiding the underlying writer object  
Public class FJsonStringReader    
Public class TJsonReader    
Public class TJsonReaderFactory    
Public class TJsonStringViewReader    
Public class TJsonStringWriter    
Public class TJsonWriter Template for Json writers.  
Public class TJsonWriterFactory    
Public struct TPrettyJsonBag
