Backward Compatibility

How far an application is backward compatible depends on the way it uses hivemind. For example a web application that uses the HiveMindFilter for loading the registry and defines service and configuration points without any complex schemas or factories has a good chance to be 100% compatible.

Things that have changed

The registry build and construction process

The RegistryBuilder and related classes (ModuleDescriptorProvider) are not used in the same way as before. See NewAndNoteworthyFeaturesInAnnotationBranch for examples how the registry is build.

Unique attributes and key-attributes

Configurations no longer limited to lists

These interfaces have changed. Items that were of type java.util.List before are now of type Objec:

• ServiceInterceptorFactory
  public void createInterceptor(InterceptorStack stack, Module invokingModule, Object parameters);
