>
> Key: CAMEL-2921
> URL: https://issues.apache.org/activemq/browse/CAMEL-2921
> Project: Apache Camel
> Issue Type: Improvement
> Components: camel-core
> Reporter: Mark Proctor
> Assignee: Hadrian Zbarcea
> Fix For: 3.0.0
>
>
> It would be nice if we could customise DataFormatDefinitions inline:
> marshal( "jaxb?contextPath=org.domain.package" )
> Here is an outline of some code I think that would achieve this, however to
> be safe (imho) the resolver should only ever returned "cloned" copies of any
> registered DataFormatDefinition; to save the originally source from being
> altered.
> I found this library (BSD license) that provides for reflection based cloning:
> http://commonj.googlecode.com/svn/trunk/src/org/jcommon/clone/
> Based on a blog I read here:
> http://www.matthicks.com/2008/05/fastest-deep-cloning.html
> DataFormatDefinition
> {code}
> public static DataFormat getDataFormat(RouteContext routeContext,
> DataFormatDefinition type, String ref) {
> if (type == null) {
> ObjectHelper.notNull(ref, "ref or type");
>
> // try to let resolver see if it can resolve it, its not always
> possible
> int pos = ref.indexOf( '?' );
> if ( pos < 0 ) {
> type =
> routeContext.getCamelContext().resolveDataFormatDefinition( ref );
> } else {
> type =
> routeContext.getCamelContext().resolveDataFormatDefinition( ref.substring(0,
> pos -1 ) );
> }
> if (type != null && pos >= 0 ) {
> try {
> Map<String, Object> parameters = URISupport.parseQuery(
> ref.substring( pos ) );
> try {
>
> IntrospectionSupport.setProperties(routeContext.getCamelContext().getTypeConverter(),
> type, parameters);
> } catch (Exception e) {
> throw new RuntimeException( "Unable to set
> DataFormatDefinition properties '" + ref + "'", e);
> }
> } catch (URISyntaxException e) {
> throw new RuntimeException( "Unable to parse parameters "
> + ref, e);
> }
>
> return type.getDataFormat(routeContext);
> }
> DataFormat dataFormat =
> routeContext.getCamelContext().resolveDataFormat(ref);
> if (dataFormat == null) {
> throw new IllegalArgumentException("Cannot find data format
> in registry with ref: " + ref);
> }
> return dataFormat;
> } else {
> return type.getDataFormat(routeContext);
> }
> }
> {code}
