Subject [jira] Commented: (CAMEL-3285) Create a new blackbox component which can encapsulate routes using a specialized ProtocolBuilder endpoint (similar to RouteBuilder)
Date Sun, 30 Jan 2011 13:44:44 GMT

Ashwin Karpe commented on CAMEL-3285:
-------------------------------------

Kristof,

Your suggestion above has the implication of a 1:1 indirection i.e the addToCatalog endpoint
will only indirect to the seda:addToCatalog route. It does not have the ability to perform
content based routing to inner routes based on payload content.

Secondly, it is perfectly legal to have multiple consumers with
          from("direct:addtoCatalog")... 
          from("seda:addtoCatalog")...
                    and
          from("http://localhost:9000/addToCatalog) in the routebox at the same time.

How would you then indirect to the right route...? I am sure your usecase can be satisfied
in the current implementation with a dispatchMap  the Routebox URI referring to a Spring defined
Hashmap if the developer is averse to writing code.

I am afraid further simplification is a behavioral change that impacts capability and serves
to confuse.  

Cheers,

Ashwin...

> Component requirements:
>  Need a Camel component (called Backbox, maybe) that can nicely expose a ProtocolBuilder
endpoint that does the following
>     a> Instantiate route definitions/route(s) configured in Spring or DSL at startup
>     b> Launch a Producer or Consumer with a well known protocol(s) so that a client
can invoke it (could be direct or seda initially but could be any protocol... really) . Must
support multiple consumer endpoints and routes using a URI scheme.
>     c> redirect received payloads (with marshalling into an exchange if necessary)
to the inner route(s) since they are launched and started. If there are multiple inner routes
with many consumers, we could expect the user to provide a clue using the payload and/or an
exchange property as to how the payload should be routed.
>     d> Extend from a Default Consumer, Producer, Endpoint and Component.
>     e> Internally manage inner route lifecycles and operations.
