Interface ComponentClient

All Known Implementing Classes:
ComponentClientImpl
public interface ComponentClient
Utility to send requests to other Kalix components by composing a DeferredCall. To compose a call:
  1. select component type (and pass id if necessary)
  2. select component method, by using Java method reference operator (::)
  3. provide parameters (if required)

Example of use on a cross-component call: 


 public Effect<String> createUser(String userId, String email, String name) {
   //validation here
   var defCall = componentClient.forValueEntity(userId).call(UserEntity::createUser).params(email, name);
   return effects().forward(defCall);
 }
