How to force compilation of a Blueprint class


just a quick question: How can i force a specific blueprint class to be recompiled (kismetcompiler) so its pins are rebuilt? Where would be a good point to start?
I cannot figure out how to start the compilation process.
I do Modify() the blueprint, but it seems i have to tell the editor to really recreate the graphs. But how??

nvm, found it.
