Claus Ibsen commented on CAMEL-1537:
------------------------------------
If the {{validate}} DSL just leverages an {{org.apache.camel.Expression}} then
we can hook in all kind of _shit_ to be validated.
You just use {{PredicateBuilder.toPredicate}} to convert the {{Expression}} to
a predicate which then returns {{true}} or {{false}}.
Then its just a matter of thrown {{ValidationException}} if the validation
failed, predicate was false.
Then as the examples shown above, its just a matter of adding fluent builders
for that in Java DSL. And have some way of doing it in Spring XML as well.
> Predicate for validation
> -------------------------

> Key: CAMEL-1537
> URL: https://issues.apache.org/activemq/browse/CAMEL-1537
> Project: Apache Camel
> Issue Type: New Feature
> Affects Versions: 2.0-M1
> Reporter: Claus Ibsen
> Assignee: Christian Mueller
> Priority: Minor
> Fix For: Future
>
>
> The current validator is a component and its a bit clumsy as it throws an
> exception if validation error.
> So if we have a nice Predicate for it, it can be like a xpath predicate or
> the likes.

> [17:58] <ulhasb> jstrachan: thanks for the quick responses
> [17:59] <cibsen> jstrachan we should maybe have a predicate for schema
> validation
> [17:59] <cibsen> then you can route it a bit more nice without try .. catch
> [18:00] * fbolton has quit ("Leaving.")
> [18:03] * gertv has quit (Client closed connection)
> [18:05] <jstrachan> cibsen: yeah
> [18:05] <jstrachan> cibsen: maybe a kinda predicate language using the other
> validators? filter().validate(theValidationEndpointUri).to("blah")
