-------------------------------------

             Summary: create an extension of the RX Observable<T> to add more 
of the Camel DSL in there (e.g. to() or to go back to the general camel DSL)
                 Key: CAMEL-7833
                 URL: https://issues.apache.org/jira/browse/CAMEL-7833
             Project: Camel
          Issue Type: New Feature
            Reporter: james strachan


with Camel RX and java 8 we can do some nice lambdas and typesafe filtering and 
transformation:
{code}
ReactiveCamel rx = new ReactiveCamel(camelContext);
Observable<Order> observable = rx.toObservable("seda:orders", Order.class);
 
// now lets filter and map using Java 8
Observable<String> largeOrderIds = observable.
  filter(order -> order.getAmount() > 100.0).
  map(order -> order.getId());
 
rx.sendTo(observable, "activemq:MyQueue");
{code}
however the DSL isn't quite as nice as Camel's due to the lack of the camel 
verbs like "to()". It'd be nice to provide an extended Observable<T> interface 
which adds more of Camel's DSL in there too; so you can still use things the RX 
way; but can also reuse the camel DSL too (in a typesafe way). 

e.g. something like this
{code}
// Observable comes from RX; it'd be nice to have a camel extended version so 
we can add camel DSL stuff in there like to() etc....
CamelStream<Order> orders = rx.stream("seda:orders", Order.class);
 
// now lets filter and map using Java 8
orders.
  filter(order -> order.getAmount() > 100.0).
  map(order -> order.getId()).
  to("activemq:MyQueue");
{code}
