I don't think this particular interface would work in C++ (we're dealing
with either FIX::FieldBase or std::string objects and there is no "null").
It would be possible to provide some additional getField/setField overloads
in FieldMap that would do what you want though:

namespace FIX {

struct nothrow {};

class FieldMap {
...
bool getField (FieldBase& field, nothrow) // doesn't throw; returns true is
hasField (field)
bool getField (int field, std::string&) // doesn't throw, returns true if
hasField (field)

I can't really see the value in them, but these could also be added:

bool setField (const FieldBase&, nothrow) // doesn't throw (and has no
effect) if value is empty
bool setField (int field, const std::string& value, nothrow) // same as
above

If people really want these interfaces they'd be very simple to add.
