Class ProviderBundle

java.lang.Object

com.gwtplatform.common.client.ProviderBundle

Direct Known Subclasses:

ProxyCodeSplitBundle.NoOpProviderBundle

public class ProviderBundle
extends Object

This class can be used to contain a group of providers that should all sit behind the same split point. That is, if the code for one provided object is loaded, so is the code for the others. This is useful when the provided objects share the bulk of their code, which would end up in the left-overs if the objects were behind their individual split points. GWTP automatically handles ProviderBundles when used with ApplicationController and Ginjector generation.

Here is an example use of a manual ProviderBundle:

 public class MyPresenterBundle extends ProviderBundle {
   public final static int ID_Object1 = 0;
   public final static int ID_Object2 = 1;
   public final static int BUNDLE_SIZE = 2;

   @Inject
   MyPresenterBundle(
       final Provider object1Provider,
       final Provider object2Provider) {
     super( BUNDLE_SIZE );
     providers[ID_Object1] = object1Provider;
     providers[ID_Object2] = object2Provider;
   }
 }
