Cover Finder

Cover finder is a java library for get a music cover from cover services, the library can iterate over diferent cover services searching the cover.

Search over diferent cover services
Add other cover services

How its works

Search a cover:

//Define the services to use

ICoverService lastFM =  new LastFmCoverService("your-api-key","your-secret");
ICoverService iTunes = new ITunesCoverService();

//Add the services to the invoquer
InvokerService invoquer = new InvokerService();
invoquer.addCoverService(lastFM);
invoquer.addCoverService(iTunes);

//Perfom the seearch
CoverResult cover = invoquer.execute("Master of puppets","Metallica");

If the invoquer not found the cover in the first service it will search in the second service and successively.

Providers

The providers use the cover service to get the cover in a especific format or using some extra funcionallity, you can create your own providers and using it in your especific applications. For instance mi application need a input stream of the cover and if the invoquer have not cover i need a default image,there is a example in the Using a provider secction

Using a provider

You can use a provider to get the cover in expecific format, by default the input stream provider is included, this provider use a UrlHandler to get a inputStream from url and a folderHandler to get a image from a local folder:

 //Define objects

        //Define all services

        ICoverService lastFM =  new LastFmCoverService("your-api-key","your-secret");       
        ICoverService iTunes = new ITunesCoverService();

        //Create invoker

        InvokerService invoquer = new InvokerService();

        invoquer.addCoverService(lastFM);
        invoquer.addCoverService(iTunes);

        //Create handler
        
        URLImageHandler urlHandler = new URLImageHandler();
        CustomFolderImageHandler customFolderHandler = new CustomFolderImageHandler();


        InputStreamCoverProvider coverProvider = new InputStreamCoverProvider(invoquer,urlHandler,customFolderHandler,"testFolder/test.png",InputStreamCoverProvider.MEDIUM_SIZE);


        InputStream imageStream = coverProvider.getCover("Fake name","Fake Artist");
