[jira] Closed: (LANG-566) Replace lastIndexOf methods with -ve

Henri Yandell closed LANG-566.
------------------------------
Resolution: Won't Fix
Thanks for the comment Chandrashekar - exposes this as a mislabeled idea.
That's what Paul and I get for dumping a random idea from a conversation.
The notion is to support negative indices - i.e. "foo"[-1] or "foofoofoo"[3:-4].
indexOf is the wrong method though, a negative index doesn't make sense there.
I'm going to close as wontfix. The above two would equal negative handling versions of charAt and substring, but I don't think it's a needed enough idea.

------------------------------------
Anything you can do to the front of the string, you can also do to the end of the string. I like the negative aspects of this (pun intended), but it doesn't guard against mathematical mistakes.
