[doc issue] filter ordering

Expected Behavior

The documentation should clarify what addFilterBefore means. For example, if the we have filter chain is A → B → C and we call addFilterBefore(X, C.class), is the result A → B → X → C or A → X → B → C or X → A → B → C . all of them follow the rule of ( X before C ) ? so i think we need some clarifications for addFilterBefore and addFilterAfter cases

Current Behavior

The documentation only says that

#addFilterBefore(Filter, Class<?>)adds your filter before another filter #addFilterAfter(Filter, Class<?>) adds your filter after another filter

which does not make the exact ordering guarantee clear.
