is it possible to simply serialize C++ objects

Question

Can you cast an object to a string of hex data (similar to how packets are sent) and then store that and then cast the object back? I know its possible with C structs which are basically objects undearneath in C++.

Compatibility of the serialization across different systems isn't important.

auto obj = new Something();

auto objHex = (unsigned char*) obj;

// store objHex in like a db
// retrieve objHex

auto obj2 = new Something();  // allocate
*obj2 = (Something*) objHex;  // set the dereference

Answer 1

No. Reasons:
a) Dynamic allocated memory, ie. pointer in the struct/class.
b) Endianess, int-size, padding etc. of the struct, order of the members...

Other things:
"If" it would be possible, there is no reason to create a full object
with constructor call before overwriting it.
And in my opinion, you′re overusing auto.
