[Swig-user] cannot replace default __str__ method

[Shields, D. P.(Technology) <Dan...@gs...>]

I'm generating java and python wrappers for an application written in
C++.
I have a template:

%rename (toString) field<std::string>::operator const std::string&;
%template (StringField) field<std::string>;

This works fine for java and allows me to print a StringField as if its
a string. The same trick for python doesn't work:

%rename (__str__) field<std::string>::operator const std::string&;

I have also tried %extend to add a __str__ function but I always
get the default SWIG implementation "<SWIG Object of type...".

What am I doing wrong?
