Reusing getters for every property of a class. (For verifying an object state.)

I have a fairly complicated Matlab class with many properties, which are classes themselves.

In total, the amount of properties in my structure is about 200.

I need the user (caller) of the to set them all, but because there are so many of them, it is very easy to forget some.

Initially every property is set to NaN, and what I want is to have a check on every access to every property:

if isnan( this.%property_name%)

error( '%property_name% is unset )

end

So that the user would be able to have some feedback, istead of having to dig through the code with a debugger.

Is there any convenient way of achieving this?ge
