-------------------------------------------------------------------
The reenginering provides both, with the new {{TypeConversionHandler}} :
{code:java}
public interface TypeConversionHandler
{
boolean isExplicitlyConvertible(Type formal, Class actual, boolean
possibleVarArg);
Converter getNeededConverter(Type formal, Class actual);
void addConverter(Type formal, Class actual, Converter converter);
}
{code}
And you can give Velocity the former (now deprecated in the branch)
{{ConversionHandler}} or the new one in the
{{runtime.conversion.handler.class}} property.

> Project: Velocity
> Issue Type: Improvement
> Components: Engine
> Affects Versions: 2.0
> Reporter: Thomas Mortagne
> Priority: Major
> Fix For: 2.0
>
>
> I was happy to see that method arguments conversion has been added to 2.0 so
> that I can remove the uberspector we have on XWiki side but unfortunately
> ConversionHandler is limited to classes which is way too restrictive for us
> (for example if the parameter type is List<String> it won't do the same thing
> than if the type is List<Integer>).
> Our uberspector can be found on
> https://github.com/xwiki/xwiki-commons/blob/master/xwiki-commons-core/xwiki-commons-velocity/src/main/java/org/xwiki/velocity/introspection/MethodArgumentsUberspector.java
> to see what we do exactly.
