Package org.kie.internal.runtime.manager

Interface WorkItemHandlerProducer

public interface WorkItemHandlerProducer
Allows to provide custom implementations to deliver WorkItem name and WorkItemHandler instance pairs for the runtime.
It will be invoked by RegisterableItemsFactory implementation (especially InjectableRegisterableItemsFactory in CDI world) for every KieSession. Recommendation is to always produce new instances to avoid unexpected results.
