< p >
< ul >
2002-09-29 03:24:20 -04:00
< li > CharRange.UNSET - will have problems if we introduce reverse ranges that go down to \u0000.< / lI >
< li > Null effects - the classes are not standardised in how they handle null.< / li >

< h3 > 5. ACTION ITEMS< / h3 >
< p > Want to help? Here's some "to do" items the team has identified. Note that all are
still under discussion, so please mail the list before actioning.< / p >
< ul >
< li > Reflection utilities - new sub-package to deal with reflection< / li >
< li > Operating system information - maybe part of SystemUtils, maybe another project< / li >
< li > MathUtils - possible addition of mathmatics helper. Could go in NumberUtils< / li >
2002-11-14 17:01:27 -05:00
< li > Fractions< / li >
2002-08-25 18:18:24 -04:00
< li > CalendarUtils - possible addition of a calendar utility class (from Serge Knystautas)< / li >
2002-11-14 17:01:27 -05:00
< li > DateRange< / li >
2002-09-21 04:11:18 -04:00
< li > CloneUtils - utility class to enable cloning via various different mechanisms. This code exists in [pattern] at present.< / li >
2002-09-19 03:02:30 -04:00
< li > StringUtils truncateNicely method - A substring with some extra power to choose where to cut off. It was in Avalon and was added separately to String Taglib from a code submission. This suggests it may have some commonality. [CODED]< / li >
2002-09-17 06:58:37 -04:00
< li > StringUtils unescape method - String Taglib has shown that this method is missing from StringUtils. It would take a String with "\n" in and convert it to the Java character. unescape and escape should be symmetric. < / li >
2002-09-18 15:50:35 -04:00
< li > ArrayUtils - opinion seems to be that this belongs with [lang] and not [collections]
2002-09-21 04:11:18 -04:00
< li > GUID and other Identifier generators - these may belong in [util], some code exists in [pattern] at the moment
< li > CharUtils - Utilities to work on a char[] in the same way as a String
< li > AStringBuffer - A StringBuffer implementation with additional methods from StringUtils
2002-09-29 03:24:20 -04:00
< li > O(n) - Document all algorithm-implementing methods with the order. Possibly with an O(n) on the end of each parameterm or with an @order tag.< / li >
2002-11-14 17:01:27 -05:00
< li > Money and Currency< / li >
< li > ExceptionUtils - truncated stack trace, from Dmitri< / li >
