I am wondering if there is an easy way to save and load a decorated object in c++ as i have never done file handling in C++ before. Currently the only object type I need to save is objects that stores values for health, damage etc. and each of these objects has at least 1 decorator. I know i could make an save function for each of the classes however I'm unsure how I would load the object.Edit: The way that i have set up the decorator is like so. new Champion(new Monster()) where the Champion is the decorator.
Is it possible to save and load a decorated object
c++;file handling;decorator
Writing objects of any kind to a file (whether decorators are involved or not) requires serializing those objects somehow, and loading them later requires deserializing them. Most of the time, (de)serializing objects means converting them to and from strings.You appear to be asking how to serialize objects. For most simple objects, this is very straightforward and you can pretty much do whatever you want. For instance, you might choose to serialize a std::tuple with 0, 1 and 2 as the string <0,1,2>. For some objects, like TCP sockets, serialization is inherently impossible, though you may be able to serialize some related information like what IP addresses they were connected to.In principle, decorators shouldn't make this more difficult. At most they might increase the number of (de)serialization methods you need to implement. We may need more information about your objects to figure out why you're stuck.If you're asking for common approaches to serializing more complex objects, or large collections of objects, I would suggest looking at the JSON and XML formats. There are plenty of libraries for generating and parsing them.
