  • Method Details

    • getField

      protected static <T> T getField(Field field, Object obj, Class<T> type)

    • execute

      public O execute(I request)
      Executes HTTP request synchronously
      Specified by:
      execute in interface OpenAIHttpExecutor<I extends Streamable,O extends Mergeable<O>>
      Parameters:
      request - The request (Input) model
      Returns:
      deserialized HTTP Response in the Output model

    • executeAsync

      public void executeAsync(I request, Consumer<String> callBack, Consumer<O> finalizer)

      Executes HTTP request asynchronously. Since response can be streamed, it can be potentially beneficial for the developer, to subscribe to each line, hence the callback parameter.

      It makes a little bit more sense to subscribe, to the whole response, using the finalizer parameter.

      Specified by:
      executeAsync in interface OpenAIHttpExecutor<I extends Streamable,O extends Mergeable<O>>
      Parameters:
      request - The request (Input) model
      callBack - A callback of type stringLine -> consume(stringLine)
      finalizer - A callback of type outputModel -> consume(outputModel)

    • executeReactive

      public OpenAIHttpExecutor.ReactiveExecution<O> executeReactive(I request)

      Executes HTTP request in reactive fashion. We strongly recommend to use this only if a real reactive runtime is present, such as Reactor netty.

      Specified by:
      executeReactive in interface OpenAIHttpExecutor<I extends Streamable,O extends Mergeable<O>>
      Parameters:
      request - The request (Input) model
      Returns:
      OpenAIHttpExecutor.ReactiveExecution<O extends Mergeable<O>> object holding a single observable (reactor.core.publisher.Mono<O extends Mergeable<O>>) to the whole response, and a multi-emit observable (reactor.core.publisher.Flux<String>) to each response line.

    • canStream

      public boolean canStream(I input)

      Denotes whether the response can be streamed, mostly taking into account the value of Streamable.stream() which usually is implemented like inputModel -> inputModel.stream() invalid input: '&'invalid input: '&' specificApiLogic.

      Specified by:
      canStream in interface OpenAIHttpExecutor<I extends Streamable,O extends Mergeable<O>>
      Parameters:
      input - The request (Input) model
      Returns:
      boolean saying if you can stream the response or not. Usually beneficial for internal calls like OpenAIHttpExecutor.execute(Streamable)
