Casting, reflection or?
I'm trying to write a simple lib for consuming a few JSON API endpoints and processing their contents with callbacks.
I'm trying to cast the "parsed" variable to its actual class (as it is known during runtime). Psuedo code as follows:
Is this just impossible or am I implenting this stuff wrong?
