[stringtemplate-interest] Get parameters of a StringTemplate

[palinf]

Hi,

I am trying to get the list of parameters (i.e. things which should be 
replace in the template).
The method StringTemplate.getParameter() return null when no parameters 
have been set.

I wrote this small piece of code to get them but I am sure this is not 
the way to do it.

      * private* List getParameters(StringTemplate st) {
                List chunks = st.getChunks();
                List l=* new* ArrayList();
               * for* (Iterator iter = chunks.iterator(); 
iter.hasNext();) {
                        Object element = (Object) iter.next();
                       * if* (element* instanceof* ASTExpr) {
                                ASTExpr new_name = (ASTExpr) element;
                                l.add(new_name.toString().trim());
                        }
        }
               * return* l;
        }


Is there a simplest way to do it ?

Olivier
