For service registration the sync and async API is combined in a single builder. The default for BundleContext::registerService is to register and unregister the service async. This is possible because registerService used a std::shared_ptr for the service so it can keep the service "alive" until async unregistration is completed. https://github.com/apache/celix/blob/feature/cxx_headers/libs/framework/include/celix/BundleContext.h#L72 https://github.com/apache/celix/blob/feature/cxx_headers/libs/framework/include/celix/ServiceRegistrationBuilder.h#L144 https://github.com/apache/celix/blob/feature/cxx_headers/libs/framework/include/celix/ServiceRegistrationBuilder.h#L167 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
