new NetworkReceiver()(implicit arg0: ClassTag[T])

Type Members

class BlockGenerator extends Serializable with Logging

Batches objects created by a org.apache.spark.streaming.dstream.NetworkReceiver and puts them into appropriately named blocks at regular intervals.

Abstract Value Members

abstract def onStart(): Unit

This method will be called to start receiving data.
This method will be called to start receiving data. All your receiver starting code should be implemented by defining this function.

Attributes

abstract def onStop(): Unit

This method will be called to stop receiving data.
This method will be called to stop receiving data.

def start(): Unit

Starts the receiver.
Starts the receiver. First is accesses all the lazy members to materialize them. Then it calls the user-defined onStart() method to start other threads, etc required to receiver the data.
def stop(): Unit

Stops the receiver.
Stops the receiver. First it interrupts the main receiving thread, that is, the thread that called receiver.start(). Then it calls the user-defined onStop() method to stop other threads and/or do cleanup.
def stopOnError(e: Exception): Unit

Stops the receiver and reports exception to the tracker.
Stops the receiver and reports exception to the tracker. This should be called whenever an exception is to be handled on any thread of the receiver.
