| /** |
| * Dynamic bean lookup across multiple injectors. |
| * <p><p> |
| * The {@link org.eclipse.sisu.inject.BeanLocator} lets you lookup and keep watch for bean implementations; |
| * it does this by processing binding information from one or more {@code BindingPublisher}s, such as injectors. |
| * <p><p> |
| * You can add or remove {@link org.eclipse.sisu.inject.BindingPublisher}s using the {@link org.eclipse.sisu.inject.MutableBeanLocator} |
| * view; any existing watchers or returned collections are updated to reflect the latest binding information. |
| * <p><p> |
| * {@link org.eclipse.sisu.inject.DefaultBeanLocator} will automatically add any injectors it's bound in by virtue |
| * of an injected setter. This makes it easy to share across multiple injectors with a simple instance binding: |
| * |
| * <pre> |
| * Module locatorModule = new AbstractModule() { |
| * private final DefaultBeanLocator locator = new DefaultBeanLocator(); |
| * |
| * @Override protected void configure() { |
| * bind( DefaultBeanLocator.class ).toInstance( locator ); |
| * } |
| * }; |
| * |
| * Injector injectorA = Guice.createInjector( new WireModule( locatorModule, spaceModuleA ) ); // adds injectorA to locator |
| * Injector injectorB = Guice.createInjector( new WireModule( locatorModule, spaceModuleB ) ); // adds injectorB to locator</pre> |
| * |
| * If you want to use a {@code DefaultBeanLocator} in a given injector, but don't want that injector |
| * added automatically, wrap the locator inside a provider to hide the injected setter from Guice: |
| * <p><p> |
| * <pre> |
| * bind( DefaultBeanLocator.class ).toProvider( Providers.of( locator ) );</pre> |
| * |
| * By default all bindings in an injector are separated into two partitions (default vs non-default) |
| * and ranked according to their sequence number. This is so bindings from multiple injectors can be |
| * interleaved to keep default components prioritized before non-default, while still maintaining an |
| * overall ordering between injectors. To override the default bind your own {@link org.eclipse.sisu.inject.RankingFunction}: |
| * <p><p> |
| * <pre> |
| * bind( RankingFunction.class ).to( MyRankingFunction.class );</pre> |
