I would like to load and save some objects instantiated from a classdef style class. I can use "save" and "load" when the objects exist in the workspace, but not outside.
For example, if I have a class called manager, that needs to load and save different employee classes, the employee classes will not exist in the workspace.
Do I need to write a custom save routine? Is there a way of leveraging the existing tools?
First of all, I hope I understand your question correctly.
You have something like this:
class Manager
properties
Employees
end
end
class Employee
end
You have an instance of Manager
manager = Manager();
e1 = Employee();
e2 = Employee();;
manager.Employees{1} = e1;
manager.Employees{2} = e2;
And you want to save it.
In this case, even if you don't have e1 and e2 in your workspace, save command will save them while saving Manager.
However, in order to load them correctly, you must have both Employee and Manager in your working directory. That makes sense, because there is no other way knowing what kind of class it was. In fact, you will get an error:
Warning: Variable 'manager' originally saved as a Manager cannot be instantiated as an object and will be read in as a uint32.
Warning: Variable 'e1' originally saved as a Employee cannot be instantiated as an object and will be read in as a uint32.
Warning: Variable 'e2' originally saved as a Employee cannot be instantiated as an object and will be read in as a uint32.
