java - Should "throws AuthFailureError" be included when overriding Request's getHeaders()? -


volley's documentation request's getheaders() method states:

returns list of http headers go along request. can throw authfailureerror authentication may required provide these values.

numerous examples, such this answer , this example (both of extend jsonobjectrequest) include throws authfailureerror when overriding method, despite don't throw exception neither call super inside method.

on other hand, some other examples ommit it. (which, think, perfectly fine).

as far notice, including throws authfailureerror when not needed adds more complexity code try/catch block or throws declaration needed in methods call getheaders().

is there advantage of including exception in declaration or potential risk of omitting it?
