@InteractionScope

@InteractionScope is a specialization of Scope @Scope for a component whose lifecycle is bound to the current top-level Interaction, in other words that it is private to the "current user".

Specifically, @InteractionScope is a composed annotation that acts as a shortcut for @Scope("interaction") .

@InteractionScope may be used as a meta-annotation to create custom composed annotations.

Alias for Scope#proxyMode .

Defaults to ScopedProxyMode#TARGET_CLASS .

A number of the built-in domain services uses this annotation, including Scratchpad and QueryResultsCache.

You may find that these services must be injected using the Provider idiom, not directly. For example:

@DomainService
public class SomeRepository {
   // ...
   @Inject Provider<QueryResultsCache> queryResultsCacheProvider;
}

If you forget to do this, then the framework will fail-fast with a suitable error message.
