Interface ActivatorCreator

All Known Implementing Classes:
DefaultActivatorCreator
@Contract public interface ActivatorCreator
Implementors of this contract are responsible for code-generating the Pico Activators and ServiceProviders for service types found in your DI-enabled module.

The typical scenario will have 1-SingletonServiceType:1-GeneratedPicoActivatorClassForThatService:1-ServiceProvider representation in the Services registry that can be lazily activated.

Activators are only generated if your service is marked as a jakarta.inject.Singleton scoped service.

All activators for your jar module are then aggregated and registered into a pico code-generated Module class.

      request - the request for what to generate
      Returns:
      the response result for the create operation

    • codegenInterceptors

      InterceptorCreatorResponse codegenInterceptors(GeneralCreatorRequest request, Map<TypeName,InterceptionPlan> interceptionPlans)

      Parameters:
      request - the request for what to generate
      interceptionPlans - the interceptor plans
      Returns:
      the response result for the create operation

    • toActivatorImplTypeName

      TypeName toActivatorImplTypeName(TypeName activatorTypeName)
      Generates the would-be implementation type name that will be generated if createModuleActivators(ActivatorCreatorRequest) were to be called on this creator.
      Parameters:
      activatorTypeName - the service/activator type name of the developer provided service type.
      Returns:
      the code generated implementation type name that would be code generated
