public interface FailQueueStrategy

FailQueueStrategy allows for configurable failure queues.

Method Summary

Modifier and Type	Method and Description

int	getFailQueueMaxItems(String curQueue) Determine the max number of items to keep in the failure queue.

Method Detail

getFailQueueKey

String getFailQueueKey(Throwable thrwbl,
                       Job job,
                       String curQueue)

Determine the key for the failure queue. A null return value is an indication that no failure queue is needed. Note that the default implementation (@see DefaultFailQueueStrategy) will never return null.

Parameters:

thrwbl - the Throwable that occurred

job - the Job that failed

curQueue - the queue the Job came from

Returns:

the key of the failure queue to put the job into or null

getFailQueueMaxItems

int getFailQueueMaxItems(String curQueue)

Determine the max number of items to keep in the failure queue. Returning a value less than 1 means that there is no limit.

Parameters:

curQueue - the queue the Job came from

Returns:

the max number of items to keep for the failure queue
