Bug 4166 DCR: Javadoc for implementers of a method (1GJJ5LD)
If I hover over a method which implements an interface or overrides a method I would like to see the corresponding Javadoc (unless I also added my own Javadoc). NOTES:
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/text/javadoc/CompletionEvaluator.java
buf.append('(');
			String[] types= meth.getParameterTypes();
			int last= types.length - 1;
			for (int i= 0; i <= last; i++) {
				buf.append(Signature.toString(types[i]));
				if (i != last) {
					buf.append(", "); 
				}
			}
			buf.append(')');
			return buf.toString();
		} else {
			return elem.getElementName();
		}
	}

	 * Returns true if case is handeled

	private boolean addArgumentProposals(String tag, String argument) throws JavaModelException {	
		if ("@see".equals(tag) || "@link".equals(tag)) { 
			evalSeeTag(argument);
			return true;
		} else if ("@param".equals(tag)) { 
			IJavaElement elem= fCompilationUnit.getElementAt(fCurrentPos);
			if (elem instanceof IMethod) {
				String[] names= ((IMethod)elem).getParameterNames();
				addProposals(argument, names, JavaPluginImages.IMG_MISC_DEFAULT);
			}
			return true;
