Here's a more complete example. Forgot the return
statement.
ObjectName {
String processObject(int me)
bypassing {badPlace} to goodPlace {
{{ String returnVal = "Initialize Return val for
the
visitor here"; }}
before things {{
System.out.println(things);
System.out.println(me);
}}
return String {{ returnVal}}
}
}
