Filters can either build up state within themselves or can merely block or pass objects based on a filtering algorithm.

Method Summary
`Object` | `filter(Object obj)` The main filtering method on the interface.
`void` | `reset()` Stateful filters should implement this interface to allow them to be reset to an intial state.
