["Arshad Basha (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LANG-1306?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Arshad Basha resolved LANG-1306.
--------------------------------
    Resolution: Invalid

Existing Method StringUtils.defaultString(final String str) does this job.

>
> 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"));
