  8. def createStream[T](jssc: JavaStreamingContext, publisherUrl: String, subscribe: Subscribe, bytesToObjects: Function[Array[Array[Byte]], Iterable[T]]): JavaReceiverInputDStream[T]

    Create an input stream that receives messages pushed by a zeromq publisher.

    Create an input stream that receives messages pushed by a zeromq publisher.

    jssc

    JavaStreamingContext object

    publisherUrl

    Url of remote zeromq publisher

    subscribe

    Topic to subscribe to

    bytesToObjects

    A zeroMQ stream publishes sequence of frames for each topic and each frame has sequence of byte thus it needs the converter(which might be deserializer of bytes) to translate from sequence of sequence of bytes, where sequence refer to a frame and sub sequence refer to its payload.

  9. def createStream[T](jssc: JavaStreamingContext, publisherUrl: String, subscribe: Subscribe, bytesToObjects: Function[Array[Array[Byte]], Iterable[T]], storageLevel: StorageLevel): JavaReceiverInputDStream[T]

  10. def createStream[T](jssc: JavaStreamingContext, publisherUrl: String, subscribe: Subscribe, bytesToObjects: Function[Array[Array[Byte]], Iterable[T]], storageLevel: StorageLevel, supervisorStrategy: SupervisorStrategy): JavaReceiverInputDStream[T]
