| <h1>Overview</h1> |
| Sisu is a modular <a href="http://atinject.googlecode.com/svn/trunk/javadoc/javax/inject/package-summary.html">JSR330</a>-based container that supports classpath scanning, auto-binding, and dynamic auto-wiring. |
| <p><p> |
| Sisu uses <a href="http://code.google.com/p/google-guice/">Google-Guice</a> to perform dependency injection and provide the core JSR330 support, but removes the need to write explicit bindings in Guice modules: |
| <p><pre> |
| Guice.createInjector( |
| new {@link org.eclipse.sisu.wire WireModule}( // auto-wires unresolved dependencies |
| new {@link org.eclipse.sisu.space SpaceModule}( // scans and binds @Named components |
| new {@link org.eclipse.sisu.space URLClassSpace}( classloader ) // abstracts class/resource finding |
| ) ) ); |
| </pre> |
| In the example above the {@code SpaceModule} scans the classpath using the {@code ClassSpace} abstraction. Any classes annotated with a {@code @Qualifier} annotation like {@code @Named} |
| will be bound as components, making them visible to the {@link org.eclipse.sisu.inject BeanLocator} and surrounding {@code WireModule} (constructed around the set of modules making up |
| the application; in this example there is only one, the {@code SpaceModule}). |
| <p><p> |
| The {@code WireModule} uses the Guice introspection SPI to analyze all bindings in the application and apply various rules to finish wiring the configuration. Unsatisfied {@code @Inject} |
| requirements are populated using the {@code BeanLocator} which provides a lookup service across all injectors it knows about, allowing for plugin-style solutions. As well as individual |
| components, the {@code WireModule} can satisfy requests for component collections like Lists and Maps (using {@code @Named} values as keys). It also cleans up duplicate and overridden |
| bindings, and merges {@link org.eclipse.sisu.Parameters} bindings. |
