Interface Function<T>

Type Parameters:

T -

public interface Function<T>

A function is asynchronously invoked when a response is received, complete or not.

This library supports predefined life cycle's events (@link Event} that can be used. For example, a Function can be defined for handling IOException:

 

     class Function<IOException>() {
         public void on(IOEXception ex) {
         }
     }
 

This function can be registered using the Socket.on(Function) as

 

     socket.on(new Function<IOEXception>() {
         ....
     }
 

This is the equivalent of doing

 

     socket.on(Event.ERROR, new Function<IOEXception>() {
         ....
     }
 

Anonymous functions call also be invoked if a Decoder match its type

 

     socket.decoder(new Decoder<String, POJO>(){
         @Override
         public POJO decode(Event e, String message) {
             return new POJO(message);
         }
     }
 

     .on(new Function<POJO>() {
         ....
     }
