Description

Trying to extend wadl generator is a pain today (= implies duplication). Would be great to get more protected method to do it faster.

Here some of them (well the one I hoped ):

• preEndMethod: in org.apache.cxf.jaxrs.model.wadl.WadlGenerator#handleOperation before writing </method>. That's basically the symmetric of org.apache.cxf.jaxrs.model.wadl.WadlGenerator#startMethodTag
• startMethodTag should be IMO protected too
• pre/post <request />, <response />, <resource /> (startResourceTag protected for pre part)

Basically idea is to be able to add before or after playing with super:

public class MyWadlGenerator extends WadlGenerator {
    @Override
   protected void startResourceTag(StringBuilder sb, Class<?> serviceClass, String path) {
         super.startResourceTag(sb, serviceClass, path);
        sb.append(...);
   }
}

Personally I desire it for resources and methods but request and response would be nice to have.

PS: handleGrammars is nice for its pupose IMO
