For the changing of the std::string allocator, I retypedef the std::string to my string, just like this:
namespace MyNamespace
{
template
class basic_string : public std::basic_string
{
// reimplement the typedefs and constructors.
};
typedef basic_string string;
typedef basic_string > wstring;
}
So I want the boost::filesystem use my own string type, but I met some problem:
The code like this:
namespace MyNamespace
{
struct path_traits;
typedef boost::filesystem::basic_path path;
typedef boost::filesystem::basic_path wpath;
struct path_traits
{
typedef string internal_string_type;
typedef string external_string_type;
static external_string_type to_external( const path &,
const internal_string_type & src ) { return src; }
static internal_string_type to_internal(
const external_string_type & src ) { return src; }
};
typedef boost::filesystem::basic_recursive_directory_iterator<path> recursive_directory_iterator;
typedef boost::filesystem::basic_recursive_directory_iterator<wpath> wrecursive_directory_iterator;
}
namespace boost
{
namespace filesystem
{
template<> struct is_basic_pathMyNamespace::path
{ BOOST_STATIC_CONSTANT( bool, value = true ); };
template<> struct is_basic_pathMyNamespace::wpath
{ BOOST_STATIC_CONSTANT( bool, value = true ); };
}
}
namespace MyNamespace
{
inline bool is_directory( const path & ph )
{ return boost::filesystem::is_directory<path>( ph ); }
inline bool is_directory( const wpath & ph )
{ return boost::filesystem::is_directory<wpath>( ph ); }
}
For replace all the function is a huge work, and in this way I can not replace it for I met this function:
BOOST_FILESYSTEM_DECL file_status
status_api( const std::string & ph, system::error_code & ec );
Maybe this way is too bother, I think there must be an easy way to replace the string.
Is there any way to resolve this? Thank you.
