Interface FunctionResolver

All Known Implementing Classes:

DefaultFunctionResolver

public interface FunctionResolver

FunctionResolver are useful for mapping received message with a Function. By default, only the predefined function Function.MESSAGE are automatically mapped to Function,

     Client client = ClientFactory.getDefault().newClient();

     RequestBuilder request = client.newRequestBuilder()
             .method(Request.METHOD.GET)
             .uri(targetUrl + "/suspend")
             .decoder(new Decoder<String, POJO>() {
                 @Override
                 public POJO decode(String s) {
                     return new POJO(s);
                 }
             })
             .transport(Request.TRANSPORT.WEBSOCKET);

     Socket socket = client.create();
     socket.on(Function.MESSAGE.message.name(), new Function<POJO>() {
         @Override
         public void on(POJO t) {
             response.set(t);
         }
     })
 

or when a Decoder share the same type as the defined Function. For example:

     Client client = ClientFactory.getDefault().newClient();

     RequestBuilder request = client.newRequestBuilder()
             .method(Request.METHOD.GET)
             .uri(targetUrl + "/suspend")
             .decoder(new Decoder<String, POJO>() {
                 @Override
                 public POJO decode(String s) {
                     return new POJO(s);
                 }
             })
             .transport(Request.TRANSPORT.WEBSOCKET);

     Socket socket = client.create();
     socket.on(new Function<POJO>() {
         @Override
         public void on(POJO t) {
             response.set(t);
         }
     })
 

An application can define its own Function.MESSAGE be writing the appropriate FunctionResolver. By default, the DefaultFunctionResolver is used.
