�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")'
templateclass�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��
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.
