Subject [jira] Commented: (LANG-330) Add StringBufferUtils or overload StringUtils methods
Date Tue, 20 Oct 2009 04:40:16 GMT

    [ https://issues.apache.org/jira/browse/LANG-330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12767686#action_12767686
] 

Henri Yandell commented on LANG-330:
------------------------------------

Also tempted to consider for repeat(...), 

Downside of this is that it potentially means duplicating the entire API for each method.
9 methods for join, 1 method for repeat.

Still - not sounding like enough yet to warrant the painfully named AppendableUtils.

> There's especially one group of methods you should overload with StringBuffer (or Appendable
in a special JDK5 Class?):
> StringUtils.join
> It should take a StringBuffer (/Appendable) as first Argument to which the Strings will
be added.
> Usage Example:
> StringBuffer sql = new StringBuffer("SELECT * FROM foo WHERE bar IN (");
> StringUtils.join(sql, bars, ", ");
> sql.append(") AND bar NOT IN (");
> StringUtils.join(sql, noBars, ", ");
> sql.append(");");
