Define Documentation

#define PARSE_POINTER_DEF (  T    )

Value: T*& parse_pointer(const string& s, T*& x) const { \ if (!ispointer(s)) \ parse(s,*x); \ else { \ T* ptr; \ parserfactory(s.c_str()+1).lookup_pointer(ptr); \ if (ptr) x=ptr; \ else error("StringParser: Could not get a " \ "pointer of required type from "+s); \ } \ return x; \ } Parse the given expression, assuming pointers will be represented as e.g. "&x", where x is the name of a parameter. Currently requires the & to be the first character in the string. This was once a template, but the template was replaced with a macro to avoid an "Internal compiler error" in GCC 2.95. To restore the template, just replace the first line of the define with: template <class T> and remove the backslashes and the macro calls. Definition at line 272 of file expressionparser.h.
