    • asyncLoop

      public static <PayloadT> java.util.concurrent.CompletionStage<PayloadT> asyncLoop​(java.util.function.Function<PayloadT,​java.util.concurrent.CompletionStage<PayloadT>> operation, @Nullable PayloadT firstArgument, @Nullable PayloadT onErrorAlternative, long iterations)
      Asynchronously executes operation iterations times. Every loops iteration begins when the previous one is terminated. Silently ignore the errors and on error it maps the result of the iteration to onErrorAlternative
      Type Parameters:
      PayloadT - input type for the operation
      Parameters:
      operation - operation to be ran in async
      firstArgument - argument for the first call
      onErrorAlternative - if the step results into an exception, provide this value as input for the next stage
      iterations - a positive number of iterations to be executed
      Returns:
      a CompletionStage<PayloadT> that is going to contain the output of the last operation
      Throws:
      java.lang.IllegalArgumentException - if iterations is negative

      Asynchronously executes operation iterations times. Every loops iteration begins when the previous one is terminated
      Type Parameters:
      PayloadT - input type for the operation
      Parameters:
      operation - operation to be ran in async
      firstArgument - argument for the first call
      onError - mapper to handle exceptions in the middle of the loop
      iterations - a positive number of iterations to be executed
      Returns:
      a CompletionStage<PayloadT> that is going to contain the output of the last operation
      Throws:
      java.lang.IllegalArgumentException - if iterations is negative
