Public Methods
public void onProducerEvent (ProducerContext producerContext, String producerName, String producerEventName)
Called whenever an important producer-specific event occurs. This may only be called if onProducerStart has been called, but corresponding onProducerFinishWith* method has not been called yet.
public void onProducerFinishWithCancellation (ProducerContext producerContext, String producerName, Map<String, String> extraMap)
Called once when producer finishes due to cancellation.
Parameters
| extraMap | Additional parameters about the producer. This map is immutable and will throw an exception if attempts are made to modify it. |
|---|
public void onProducerFinishWithFailure (ProducerContext producerContext, String producerName, Throwable t, Map<String, String> extraMap)
Called when producer finishes processing current unit of work due to an error.
Parameters
| extraMap | Additional parameters about the producer. This map is immutable and will throw an exception if attempts are made to modify it. |
|---|
public void onProducerFinishWithSuccess (ProducerContext producerContext, String producerName, Map<String, String> extraMap)
Called when a producer successfully finishes processing current unit of work.
Parameters
| extraMap | Additional parameters about the producer. This map is immutable and will throw an exception if attempts are made to modify it. |
|---|
public void onProducerStart (ProducerContext producerContext, String producerName)
Called whenever a producer starts processing unit of work. This method might be called multiple times, but between any two consecutive calls to onProducerStart onProducerFinishWithSuccess will be called exactly once.
public void onRequestCancellation (ProducerContext producerContext)
Called after the request is cancelled.
Parameters
| producerContext | the producer context for the image |
|---|
public void onRequestFailure (ProducerContext producerContext, Throwable throwable)
Called after failure to complete the request (some producer failed).
Parameters
| producerContext | the producer context for the image |
|---|---|
| throwable | cause of failure |
public void onRequestStart (ProducerContext producerContext)
Called when request is about to be submitted to the Orchestrator's executor queue.
Parameters
| producerContext | the producer context for the image |
|---|
public void onRequestSuccess (ProducerContext producerContext)
Called after successful completion of the request (all producers completed successfully).
Parameters
| producerContext | the producer context for the image |
|---|
public void onUltimateProducerReached (ProducerContext producerContext, String producerName, boolean successful)
Called when the producer which can create the final result for a given request has completed.
This can be used to determine which producer was best able to satisfy the request.
