T- type of emitted items
public class ParallelStreamP<T> extends AbstractProcessor
|Constructor and Description|
Creates a processor that generates items using its assigned generator functions.
|Modifier and Type||Method and Description|
Called after all the inbound edges' streams are exhausted.
Method that can be overridden to perform any necessary initialization for the processor.

false, it will be invoked again until it returns
true. For example, a streaming source processor will return
falseforever. Unlike other methods which guarantee that no other method is called until they return
Processor.saveToSnapshot()can be called even though this method returned
After this method is called, no other processing methods are called on
this processor, except for
Non-cooperative processors are required to return from this method from time to time to give the system a chance to check for snapshot requests and job cancellation. The time the processor spends in this method affects the latency of snapshots and job cancellations.
