Class DefaultModelProcessor

java.lang.Object
org.apache.maven.impl.model.DefaultModelProcessor
All Implemented Interfaces:
org.apache.maven.api.services.model.ModelProcessor
@Named @Singleton public class DefaultModelProcessor extends Object implements org.apache.maven.api.services.model.ModelProcessor
Note: uses @Typed to limit the types it is available for injection to just ModelProcessor. This is because the ModelProcessor interface extends ModelLocator and ModelReader. If we made this component available under all its interfaces then it could end up being injected into itself leading to a stack overflow. A side effect of using @Typed is that it translates to explicit bindings in the container. So instead of binding the component under a 'wildcard' key it is now bound with an explicit key. Since this is a default component; this will be a plain binding of ModelProcessor to this implementation type; that is, no hint/name. This leads to a second side effect in that any @Inject request for just ModelProcessor in the same injector is immediately matched to this explicit binding, which means extensions cannot override this binding. This is because the lookup is always short-circuited in this specific situation (plain @Inject request, and plain explicit binding for the same type.) The simplest solution is to use a custom @Named here so it isn't bound under the plain key. This is only necessary for default components using @Typed that want to support overriding. As a non-default component this now gets a negative priority relative to other implementations of the same interface. Since we want to allow overriding this doesn't matter in this case. (if it did we could add @Priority of 0 to match the priority given to default components.)
