Claus Ibsen commented on CAMEL-2244:
------------------------------------
Cool, I think we should look into camel-jetty and see if it cannot use this new
feature instead of its own logic. It has such a feature for security handlers.
> Support for processing list-based reference params in DefaultComponent.

> Key: CAMEL-2244
> URL: https://issues.apache.org/activemq/browse/CAMEL-2244
> Project: Apache Camel
> Issue Type: Improvement
> Affects Versions: 2.1.0
> Reporter: Martin Krasser
> Assignee: Martin Krasser
> Priority: Minor
> Fix For: 2.2.0
>
>
> Add a new method
> {noformat}
> <T> List<T> resolveAndRemoveReferenceListParameter(Map<String, Object>
> parameters, String key, Class<T> elementType, List<T> defaultValue)
> {noformat}
> to DefaultComponent for processing list-based reference params. Here's an
> example of a Spring application context with bean definitions followed by
> URIs that reference these beans.
> {code:xml}
> <bean id="filter1" class="..."/>
> <bean id="filter2" class="..."/>
> <util:list id="filterList">
> <ref bean="filter1" />
> <ref bean="filter2" />
> </util:list>
> {code}
> The new {{resolveAndRemoveReferenceListParameter}} handles the following
> cases.
> Resolve reference to a bean of type java.util.List and return that list.
> {noformat}
> from("mina:tcp://localhost:6142?filters=#filterList")
> {noformat}
> Resolve reference to a bean of type {{elementType}} (see method signature)
> and return a list containing that element.
> {noformat}
> from("mina:tcp://localhost:6142?filters=#filter1")
> {noformat}
> Resolve comma-separated reference list to beans of type {{elementType}} (see
> method signature) and return a list containing these elements.
> {noformat}
> from("mina:tcp://localhost:6142?filters=#filter1,#filter2")
> {noformat}
