public class YamlWriter extends org.apache.camel.support.service.ServiceSupport implements org.apache.camel.CamelContextAware
YAML writer which uses Jackson to dump to yaml format. Implementation notes: This writer is based on the same principle for the XML writer which parses the Camel routes (model classes) and emit a StAX based events for start/end elements. However since the YAML DSL is not as easy to dump as XML, then we need to enrich with additional metadata from the runtime catalog (EipModel). We then abuse the EipModel and store the route details in its metadata. After this we transform from EipModel to EipNode to have a List/Map structure that we then transform to JSon, and then from JSon to YAML.
