> Add nullToEmpty method in StringUtils
> -------------------------------------
>
> Key: LANG-1306
> URL: https://issues.apache.org/jira/browse/LANG-1306
> Project: Commons Lang
> Issue Type: New Feature
> Components: lang.*
> Reporter: Arshad Basha
> Priority: Minor
> Fix For: 3.6
>
>
> 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"));
