I want to serialize objects that link to each other through pointers, like a
linked list, but in this case a more complex graph with several different
classes and proxies (a graph which can contain loops and and null-pointers).
But I get the "pointer conflict" exception since the serialization discovers
that an object have been serialized once before through its pointer. The
contents should be serialized/deserialized only once, and then the pointers
should just be kept consistent.
An alternative is of course to replace all the pointers with indeces which are
memory-independent. But that's a messy affair.
In the copy constructor I solved something similar through a map<Type*,Type*>
which mapped from the old pointers to the newly allocated ones, so that they
could be properly replaced. Is something like this hidden somewhere in the lib?
