[jira] [Commented] (CAMEL-4807) intercept() doesn't store intercepted endpoint in Exchange.INTERCEPTED_ENDPOINT

    [ https://issues.apache.org/jira/browse/CAMEL-4807?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13179716#comment-13179716 ] 

Raul Kripalani commented on CAMEL-4807:
---------------------------------------

After investigating this ticket it looks like storing the intercepted endpoint would not align with the functionality of intercept().

By nature, intercept() intercepts Processors and while there are a number of out-of-the-box processors which ultimately interact with endpoints (SendProcessor, RecipientListProcessor, MulticastProcessor, etc.). This set isn't fix and keeps on increasing as we add functionality to Camel. Additionally, the end-user may implement custom processors. So all in all, extracting the endpoint URI(s) from all of them is definitely not the way to go.

My intention was really to provide more richness of runtime routing information to the user, to enable them to implement dynamic interceptors that may act differently based on where the exchange is right now.

For example, if custom node IDs have been set along the route, they should be injected in a message header as part of the interception.
We could also add the shortName or the label of the target processor to enable the user to react differently if the target processor is an Aggregation, Delay, ThrowException, etc.

If this idea is accepted, I will go ahead and implement it.

> The intercept() DSL doesn't seem to store the intercepted endpoint (if the original intended destination at that point is an endpoint) in the Exchange.INTERCEPTED_ENDPOINT property.
> This could be useful if you want to build generic interceptor logic which has the capability of taking decisions based on if the next processor is a specific endpoint.
