>
> CAMEL-10447 has introduced InputType/OutputType declaration and declarative
> Transformer/Validator based on those types declared on a route.
> Next step is to provide type metadata for each Components/DataFormats:
> * Let components/DataFormats provide metadata about what data types are
> supported so that app developer can see
> * Narrow down the possible data types (i.e. exclude unsupported types) and
> transformers when writing a route in IDE, allow IDE to show those candidates
> as a hint so that app developer can choose from. Also maven plugin could
> leverage those metadata
> * Provide such facility from camel side so that the maven plugin and/or IDE
> can leverage it
> Annotation would be an option, but it only provides static types. For example
> xslt component only consumes/produces XML so "XML" could be provided via
> annotation. But dozer component consumes/produces arbitrary data formats and
> the actual type to be used is determined via configuration, so it cannot be
> provided via annotation. It would need a common way to calculate possible
> input types and output types on a component/endpoint and dataformat from its
> configuration.
> Sometimes even body of the input message would affect the possible output
> types. To visualize this we'll need some kind of simulation with a test
> message.
