- Method Detail
  - decodeValue
```
public static Object decodeValue(Type type,
                                 JsonValue jsonValue,
                                 Object target,
                                 ApplicationConnection connection)
```
    Decode a JSON array with two elements (type and value) into a client-side type, recursively if necessary.
    
    Parameters:
    
    jsonValue - JSON value with encoded data
    
    connection - reference to the current ApplicationConnection
    
    Returns:
    
    decoded value (does not contain JSON types)
  - obj2jso
```
public static <T extends JsonValue> T obj2jso(Object object)
```
    Called by generated deserialization code to treat a generic object as a JsonValue. This is needed because GWT refuses to directly cast String typed as Object into a JSO.
