Examples of org.apache.camel.processor.loadbalancer.FailOverLoadBalancer

org.apache.camel.processor.loadbalancer.FailOverLoadBalancer
This FailOverLoadBalancer will failover to use next processor when an exception occurred
This implementation mirrors the logic from the {@link org.apache.camel.processor.Pipeline} in the async variationas the failover load balancer is a specialized pipeline. So the trick is to keep doing the same as the pipeline to ensure it works the same and the async routing engine is flawless.
