gson - Deserialising a generic with unknown compile time type where a field indicates the type -

-

This works but it's awesome - is there a better way?

I have a general category that is in this simple example as follows 

  Public Class Messaggraph & lt; T & gt; {@ Apply personalized T-message; Give an example of @ personal string type; Private string uri; }   
 serialising is bad but trivial, eg,  
  type type = new TypeToken. & Lt; MsgWrapper & LT; Information & gt; & Gt; () {} GetType () .; Gson.toJson (message, typeToken);   
 The server receives JSO which can either  
  Messaging < Notice & gt; On this message & lt; Alert & gt;   
 If it notices 'will type' field 'notice' if it is a warning call 'type' field 'alert'  
 At the moment I  
  public MsgWrapper deserialize (JsonElement json, type typeOfT, JsonDeserializationContext context) throws JsonParseException {JSONObject object = json.getAsJsonObject () is executing a custom Deserialiser; If (object.has ("type")) {messagegrapper msgWrapper = new msgwrapper (); MsgWrapper.setType (object.get ("type") getAsString ().); If (MsgWrapperkgetType (). Equals ignore CAS ( "Notice")) {msgWrapper.setMessage (context.deserialize (object.get ( "message"), notice. Square)); } Else if (msgWrapper.getType () equalsIgnoreCase ( "Warning").) {MsgWrapper.setMessage (context.deserialize (object.get ( "message"), Alert.class)); } Return msgWrapper; } And (new) JsonParseException ("Something is wrong ..."); }}}   
 Does this feel a mess and mess is there any better way?   
 
 
 The solution that you have posted is as good as the least as good as the current Gson release is regarded as polymorphic assertion.  
 You can apply the suggestions with the custom deserializer some small changes to external configuration, refer to the change donations to use as along the lines  Maps & lt; String, deserializer & gt;   
 Instead of using a custom deserializer, so Gson will soon  look for RuntimeTypeAdapter  Simple polymorphic deserialization. See for more information, even if you can not use the  RuntimeTypeAdapter , it provides at least one instance to create a configuration custom deserializer.  
 JSON mapping can switch APIs, so I recommend to consider Jackson, as there is a work and relatively simple polysulfin deserializer system available in it. I posted a few simple examples

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
