      Optional subclass override hook to allow for advanced Engine configuration.

      Simple embeddings can leave this alone. Complex embeddings can either set the engine via setEngine() or override this method to construct/configure as needed.

      This default implementation constructs an Engine with the supplied configProfile and adds api to it if api is not null.

      If api is null, it calls buildApi() which by default does nothing and is itself designed as an override hook.

      Parameters:
      request - the request to service
      context - the execution context
      Returns:
      an Engine with an Api already set if one was supplied otherwise an empty Engine that will be configured via via Confg/Configurator.

      buildApi(HttpRequestMessage, ExecutionContext)

    • buildApi

      protected io.inversion.Api buildApi​(com.microsoft.azure.functions.HttpRequestMessage<Optional<String>> request, com.microsoft.azure.functions.ExecutionContext context)
      Optional subclass override hook to supply your own custom wired up Api.

      If you don't set your api via setApi() and you don't override buildApi() to supply an Api or otherwise wire your custom Api and Engine in an overridden buildEngine() method, you will need to define your Api in inversion.properties files for autowiring via Confg/Configurator.

      Parameters:
      request - the request to service
      context - the execution context
      Returns:
      null unless you override this method to construct an Api.
