Comment (by anonymous):

 I could derive lockable_adapter to lockable_adapter2 and use its const
 members.


 {{{

 template <typename BasicLockable>
 class basic_lockable_adapter2 :
     public boost::basic_lockable_adapter<BasicLockable>
 {
 public:
 basic_lockable_adapter2()
 {}

 void lock() const
 {
     lockable().lock();
 }
 void unlock() const
 {
     lockable().unlock();
 }

 };

 class Class1 :
     public basic_lockable_adapter2<boost::recursive_mutex>
 {
 public:
     Class1() :_i(0){}
     virtual ~Class1(){}

     void set(int i) {
         _i = i;
     }

     int get() const {
         return _i;
     }

 private:
     int _i;
 };
 }}}
