Subject [jira] Updated: (LANG-180) [lang] adding a StringUtils.replace method that takes an array or List of replacement strings
Date Fri, 18 Jan 2008 07:21:34 GMT


Henri Yandell updated LANG-180:

    Attachment: LANG-180.patch

I've refactored Chris' attachment as a patch file.

I've removed the boolean parameter, and suggesting names of 'replaceEach' and 'replaceEachRepeatedly'.

Tests pass happily - need to dig into the implementation code.

> I have the situation where I have a String template with a dozen replacements 
> I need to make.  When I loop through and use StringUtils.replace each time, it 
> has to make a StringBuffer of the whole template each time.  I think we could 
> make this more efficient if we had a replace() method which took an array of 
> Strings to search for, and an array of Strings to replace with (or we could 
> use a Collection or List or something).  This way we could possibly do the 
> replace in one StringBuffer result.
> One issue is if the replacement text has Strings to be replaced, do we iterate 
> through again until there are no Strings to search for?  Based on your 
> replaceChars(String str, String searchChars, String replaceChars) method, I 
> assume the answer is no, but we could have a boolean flag to have it both ways.
> I can write this for you if you are interested, please let me know.
