It's possible to provide custom project stage implementations.
Therefore, you have to provide an implementation of the ProjectStageHolder interface.
In this class you nest the custom project-stage implementations which have to be public static final class and it's required to extend ProjectStage.
It's required to provide a public static final instance even though, you won't use it directly.

Code Block
java
java
titleProjectStageHolder for custom project stage implementationsjava
public class CustomProjectStageHolder implements ProjectStageHolder
{
    public static final class CustomProjectStage extends ProjectStage
    {
        private static final long serialVersionUID = 1029094387976167179L;
    }

    public static final CustomProjectStage CustomProjectStage = new CustomProjectStage();
}

Configure your custom ProjectStageHolder in META-INF/services/org.apache.myfaces.extensions.cdi.core.api.projectstage.ProjectStageHolder. The file has to provide the fully qualified class name of the custom implementation of the ProjectStageHolder interface.

Code Block
java
java
titleUsage of a custom project stagejava
ProjectStage customProjectStage;
customProjectStage = ProjectStage.valueOf("CustomProjectStage");
//or
customProjectStage = CustomProjectStageHolder.CustomProjectStage;
//or
@ProjectStageActivated(CustomProjectStageHolder.CustomProjectStage.class)

CDI provides the mechanism of @Alternative (as well as @Specializes) implementations. As soon as MyFaces CODI provides a default implementation as CDI bean, it's possible to provide a custom implementation via @Alternative (or @Specializes) (+ the corresponding std. CDI config). However, some CDI artifacts like CDI-Extensions (javax.enterprise.inject.spi.Extension) and Interceptors (javax.interceptor.Interceptor) don't support the mechanism for providing alternative implementations. Therefore, MyFaces CODI allows to create a custom implementation of the ClassDeactivator interface (or AbstractClassDeactivator).

Code Block
java
java
titleImplementing a custom Class-Deactivatorjava
public class CustomClassDeactivation extends AbstractClassDeactivator
{
    protected void deactivateClasses()
    {
        addDeactivatedClass(DefaultImpl.class);
        //...
    }
}
