Subject [jira] [Commented] (LANG-1306) Add nullToEmpty method in StringUtils
Date Mon, 02 Jan 2017 15:56:58 GMT

    Thanks for the pull request! :)
    
    The same behavior can be achieved with `ObjectUtils.defaultIfNull(str, "")`, but of course
this new method reads much better, so I'm in favor of merging. Best as on the commons developer
list (https://commons.apache.org/proper/commons-lang/mail-lists.html) if there are any objections.

>             Project: Commons Lang
>          Issue Type: New Feature

> The nullToEmpty method will convert null reference to empty string, for non null str
it will return the str as it is (i.e. without striping or removing space)
> This method doesn't strips white-space nor removes control characters from the start
and end of the input string like StringUtils.stripToEmpty and StringUtils.trimToEmpty methods.
> This method will allow us to replace common code patterns like the following from client
side code:
> 1) if(str == null) {   str = "";  }
> 2) return str == null ? "" : str;
> Examples:
>         assertEquals("", StringUtils.nullToEmpty(null));
>         assertEquals("", StringUtils.nullToEmpty(""));
>         assertEquals("abc", StringUtils.nullToEmpty("abc"));
>         assertEquals("  abc", StringUtils.nullToEmpty("  abc"));
>         assertEquals("abc  ", StringUtils.nullToEmpty("abc  "));
>         assertEquals("abc\t", StringUtils.nullToEmpty("abc\t"));
