James Strachan commented on CAMEL-990:
--------------------------------------
BTW - its not really a big deal to use annotations from any particular
framework in your code as annotations are a soft dependency.
e.g. adding Camel annotations to your code doesn't add any direct dependency on
camel. You can then use your code totally fine without any camel jars on the
classpath.
So there's not a huge need to 'hide' dependencies on Camel annotations - as you
only need them to compile your source code.
But using indirect annotations can be useful; e.g. you can have a foo.jar which
defines a @Foo annotation which builds itself with camel - then folks can just
add foo.jar to their classpath to get camel goodness without adding camel jars
to the build. So you could introduce a kinda macro annotation that includes
various framework annotations on it (say spring and camel and guice annotations
:)
> TypeConverter support with @Converter meta-annotation and not only @Converter

> Key: CAMEL-990
> URL: https://issues.apache.org/activemq/browse/CAMEL-990
> Project: Apache Camel
> Issue Type: Improvement
> Components: camel-core
> Affects Versions: 1.4.0
> Reporter: Seb Auvray
> Fix For: 1.5.0, 2.0.0, Future
>
> Attachments: typeconverter-meta-annotation-support.patch
>
> Original Estimate: 4 hours
> Remaining Estimate: 4 hours
>
> Today TypeConverter detection is based on [EMAIL PROTECTED] annotation.
> Allow user to override this by using meta-annotation. This can be useful to
> hide camel dependencies, when extending the framework.
> ie, this can be done:
> package some.package.of.mine;
> @Retention(RetentionPolicy.RUNTIME)
> @Target({ElementType.TYPE, ElementType.METHOD })
> @org.apache.camel.Converter
> public @interface OwnConverterAnnotation {
> }
> import some.package.of.mine.OwnConverterAnnotation;
> @OwnConverterAnnotation
> public class FileToXXXConverter {
> @OwnConverterAnnotation
> public static XXX toWorkflowEntry(File file) throws IOException {
> return new XXX();
> }
> }
