Method Detail
-
init
protected void init(@Nonnull Processor.Context context)
Description copied from class:AbstractProcessor
Method that can be overridden to perform any necessary initialization for the processor. It is called exactly once and strictly before any of the processing methods (process()
andProcessor.complete()
), but after the outbox andlogger
have been initialized.Subclasses are not required to call this superclass method, it does nothing.
- Overrides:
init
in classAbstractProcessor
- Parameters:
context
- thecontext
associated with this processor
-
complete
public boolean complete()
Description copied from interface:Processor
Called after all the inbound edges' streams are exhausted. If it returnsfalse
, it will be invoked again until it returnstrue
. For example, a streaming source processor will returnfalse
forever. Unlike other methods which guarantee that no other method is called until they returntrue
,Processor.saveToSnapshot()
can be called even though this method returnedfalse
.After this method is called, no other processing methods are called on this processor, except for
Processor.snapshotCommitFinish(boolean)
.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.
- Returns:
true
if the completing step is now done,false
to call this method again
