NDK开发中使用stl中的hash_地图

#include <hash_map> namespace stdext{    template<> size_t hash_compare< std::string, std::less< std::string > >::operator ()( const std::string& _stringBase ) const    {        register size_t ret = 0;        for( std::string::const_iterator it = _stringBase.begin(); it != _stringBase.end(); ++it )            ret = 5 * ret + *it;        return ret;    }} typedef stdext::hash_compare< string, std::less< string > > StringHash;
