[Swig-user] How does swig deal with using ::std::vector in c++ header file

[xuxq <xqx...@ho...>]

Hello all,
I met problem when wrapping C++ to Ruby with SWIG related statement using ::std::vector in c++ header file. It seems that SWIG does not recognize "using ::std::vector" statement. I am using swig 2.0.8. I don't know if my have a wrong usage or SWIG does not support it.
after running the ruby script at the end, it reports "undefined method size()" for the last line.If I remove "using ::std::vector" in the header file. And change the signature of "vector<Animal> getAnimals()" to "std::vector<Animal> getAnimals()", the ruby script works good.
Can you provide any hints?
Thanks a lot!
Best Regards,Fiona Xu
Here is my .i file.%{#include "Animal.hpp"%}
%include "std_string.i"%include "std_vector.i"%include "Animal.hpp"
%template(StringVector) std::vector<std::string>;%template(IntVector) std::vector<int>;%ignore std::vector<Animal>::resize(size_type);%ignore std::vector<Animal>::vector(size_type);
%template(AnimalVector) vector<Animal>;
Here is my .hpp file.#include <string>#include <vector>
using ::std::vector;using ::std::string
class Animal{public:    Animal(std::string);    ~Animal();    std::string getName();        vector<Animal> getAnimals();}
Here is my ruby script.
cat = Example::Animal.new("cat");animal = Example::AnimalVector.new();animal.push(cat);
dog = Example::Animal.new("dog");animal.push(dog);for i in 0..1    printf "name is: %s\n", animal[i].getName();end
animals = cat.getAnimals();printf "There are : %d animals\n", animals.size;
