Date Mon, 06 Apr 2015 17:29:18 GMT


Benedikt Ritter closed LANG-1090.

> FastDateParser does not set error indication in ParsePosition
> -------------------------------------------------------------
>                 Key: LANG-1090
>                 URL:
>             Project: Commons Lang
>          Issue Type: Bug
>            Reporter: Sebb
>            Priority: Minor
>             Fix For: 3.4
> FastDateParser#parse(String,ParsePosition) does not throw ParseException if the input
cannot be matched.
> If the parse succeeds, the ParsePosition is updated to the index of the next character
after the last one used, and the error index is left as -1.
> If the parse fails, at present the ParsePosition is not updated at all, unlike SimpleDateFormat
which is able to set the error Index to the location where the error occurr.
> It does not appear to be possible to determine the error location because the matching
against the format string is all or nothing.
> This means that a successful parse can only be detected by checking whether the ParsePosition
has been updated.
> This needs to be documented, and some unit tests added.
