[jira] Commented: (LANG-510) Convert StringUtils API to take CharSequence

["Henri Yandell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12842220#action_12842220 ] 

Henri Yandell commented on LANG-510:
------------------------------------

lastIndexOf method can be CharSequence'd. Same way as indexOf for now - use toString on non-Strings to get a String and use its API. Later rewrite with a charAt algorithm.

> 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.
