Basically as the subject says, what is this function for? In order to use the InputFilterAwareInterface, I need to create a setInputFilter method. What is the purpose of that method? In the tutorials, it just throws an exception when called, I can't find any documentation for it on the ZF2 website, and in the interface itself the documentation is simply "Set input filter".
I have tried using it to add input filters, but unless I pass them as an array (not allowed by this function) they just break. What should I be using this for?
