[stringtemplate-interest] What compiles to : Bytecode.INSTR_LOAD_ATTR ?

[Collin Fagan]

Hi Everyone,

In my (probably misguided) quest to inject attributes into the scope of a
template I've overridden the getAttribute method on Interpreter. This method
call gets invoked when the Interpreter runs into Bytecode.INSTR_LOAD_ATTR.
My problem is that my simple test never generates this bytecode. It only
generates Bytecode.INSTR_LOAD_LOCAL.

Does anyone know what I have to do to generate Bytecode.INSTR_LOAD_ATTR?


Thanks,

Collin


Here is my experimental code:

/**

 */
public class Exp {

    private class ExtInterpreter extends Interpreter {

        public ExtInterpreter(STGroup group, Locale locale,
                ErrorManager errMgr, boolean debug) {
            super(group, locale, errMgr, debug);
            // TODO Auto-generated constructor stub
        }

        @Override
        public Object getAttribute(ST self, String name) {
            System.out.println(name);
            return super.getAttribute(self, name);
        }
    }

    @Test
    public void testStaticMethodAddForString() {
        STGroup group = new STGroup();
        group.defineTemplate("main", "string", "{<string.q>}");
        ST mainTemplate = group.getInstanceOf("main");
//        mainTemplate.add("string", "this is my test string");

        Interpreter interp = new
ExtInterpreter(group,Locale.getDefault(),group.errMgr,false);
        StringWriter stringWriter = new StringWriter();
        STWriter wr = new AutoIndentWriter(stringWriter);
        wr.setLineWidth(STWriter.NO_WRAP);
        interp.exec(wr, mainTemplate);
        System.out.print(stringWriter.toString());
    }
}
