public class PollEnricher
extends org.apache.camel.support.AsyncProcessorSupport
implements org.apache.camel.spi.IdAware, org.apache.camel.CamelContextAware
producer
and second by aggregating input data and additional data. Aggregation of
input data and additional data is delegated to an AggregationStrategy
object.
Uses a PollingConsumer
to obtain the additional data as opposed to Enricher
that uses a Producer
