Henri Yandell updated LANG-510:
-------------------------------
Comment: was deleted
(was: Alternatively - for now - we could merely call toString on the
CharSequence class if it's not a String.
Basically making the return str.indexOf(...) into:
{code:java}
if (str instanceof String) {
return ((String) str).indexOf(searchChar);
} else {
return str.toString().indexOf(searchChar);
}
{code}
Cost to existing String users is an instanceof check and a cast.
We could then later implement a String indexOf based on charAt and subSequence.
Or possibly just charAt if we feel subSequence is expensive.)

>
>
> Wherever possible, use CharSequence and not String in the StringUtils API.
> substring can go to subSequence inside code. The general substring method can
> be replaced with a subSequence method and substring deprecated(?). One
> question is whether to implement a CharSequence.indexOf type method. Given
> that it's merely a walking method(?!?), this might be quite handy and would
> allow a bunch of StringUtils methods to move over.
