public class FrameworkProducer
extends org.apache.camel.impl.DefaultProducer

Producer for the custom Camel CatalogComponent. This Producer would map to a Camel route node with a URI like catalog:framework. The message sent to this component should have header named "operation" with a value of "CREATE", "UPDATE" or "DELETE".

For the CREATE and UPDATE operation, the message body can contain a List of Metacards or a single Metacard object.

For the DELETE operation, the message body can contain a List of String or a single String object. The String objects represent the IDs of Metacards that you would want to delete.

The exchange's "in" message will be set with the affected Metacards. In the case of a CREATE, it will be updated with the created Metacards. In the case of the UPDATE, it will be updated with the updated Metacards and with the DELETE it will contain the deleted Metacards.

USE CASE	ROUTE NODE	HEADER	MESSAGE BODY	EXCHANGE MODIFICATION
Create Metacard(s)	catalog:framework	operation:CREATE	List<Metacard> or Metacard	exchange.getIn().getBody() updated with List of Metacards created
Update Metacard(s)	catalog:framework	operation:UPDATE	List<Metacard> or Metacard	exchange.getIn().getBody() updated with List of Metacards updated
Delete Metacard(s)	catalog:framework	operation:DELETE	List<String> or String (IDs of Metacards to delete)	exchange.getIn().getBody() updated with List of Metacards deleted
