Hello everybody,
�
I'm currently trying to serialize functors.
Apparently, it is not possible to serialize boost::function objects,
is it possible to find a way to serialize pointer to function ? (in order
to make working the example below*)
If it is definitively not possible, is there a way to 'register' a
relation betwwen objects and functor ? (using MPL library).
The idea is to rebuild the boost function according to the 'Object and
'Type' class of the template'.
�
Example:�
�
mpl::pair container;
serialize()
{
boost::function m_getter=mpl::at< container,Object>;
}
�
�
*Here is the problem that� I'm trying to resolve:
�
MyObject myObject("before");
�
SetCommandstd::string,MyObject
SetCommand(myObject,&MyObject::setName,&MyObject::getName,"after");
�
SetCommand.do(); � // call functor 'MyObject::setName("after")'
SetCommand.undo(); // call functor 'MyObject::setName("before")'
�
�
template
class SetCommand : public Command
{
�
�
� public:
�
� � � � template
� � � � SetCommand(Object& o, const Setter& setter, const Getter& getter,
const Type& value) :
� � � � � � Command(),
� � � � � � m_getter(boost::bind(getter, &o)),
� � m_setter(boost::bind(setter, &o, _1)),
� � � � � � initialValue(m_getter()),
� � � � � � finalValue(value)
� � � � {
� � � � }
�
virtual void undo()
� � � � {
� � � � � � m_setter(initialValue) ;
� � � � }
�
� � � � virtual void do()
� � � � {
� � � � � � m_setter(finalValue) ;
� � � � }
�
�� private:
�
friend class boost::serialization::access;
�
SetCommand(){}
�
template <class Archive>�
void serialize( Archive & ar, const unsigned int version )
{
�
� ar & m_getter; ERROR -> does not compile !!!
� ar & m_setter; ERROR -> does not compile !!!
�
� ar & initialValue;
� ar & finalValue;
}
�
boost::function m_getter ;
� � � � boost::function m_setter ;
�
� � � � Type initialValue ;
� � � � Type finalValue ;
};
�
Thanks in advance.
