Callback Pattern

In this project we visualize how use callbacks

By Romell Domínguez

Examples:

// java
service.needImagesForSomethig(id idTrack, String hashSecurity, new ServiceCallback(){
    public void successful(int code,Array<Bitmap> maps){

    }

    public void throwProblem(int code, ServiceException exception){

    }
} );
// kotlin
service.needImagesForSomethig(idTrack: Int , hashSecurity: String , object : ServiceCallback(){
    override fun  successful(code : Int,maps: Array<Bitmap> ){

    }

    override fun throwProblem(code: Int,  exception: ServiceException){

    }
} ) 

Simple

//java
service.returnTripleCallback(value,new OtherCallback(){

            @Override
            public void returns(int model) {
                show(MessageFormat.format("The triple of {0} is {1}", value, it));
            }
        });
//kotlin
service.returnTripleCallback(value) {
             show("The triple of $value is $it")
         }
service.returnTripleCallback(value) { it: Int, iTriple: Int ->
             show("The triple of $it is $iTriple")
         }
