I&#39;m working on integrating Boost serialization into an OMNeT++ simulation as a means of saving a partial simulation state (to speed up statistical testing). The problem I am running into is related to the process of deserializing a derived-class object by a base-class pointer without tracking.<br>
<br>As far as I can tell, in this case the serialization library normally:<br>1. Determines the most-derived type<br>2. Allocates memory for that type of object<br>3. Updates the pointer to point the the above allocated memory block<br>
4. Invokes placement new and the default constructor (overloadable by load_construct_data)<br>5. Calls the class&#39; serialize() or load() method on the newly-constructed object<br><br>However, I have a case where I start out with an existing derived-class object that is partially initialized, and I just want to call the serialize() or load() method for it using a base-class pointer (i.e., no memory allocation since that&#39;s already done, and no constructor call since that&#39;s also already done.) Is this possible or am I trying to do something the serialization library is not meant for?<br>
