<h3>4. KNOWN ISSUES</h3>
|
|
<p>
|
|
<ul>
|
|
<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>
|
|
</ul>
|
|
</p>

<h3>5. ACTION ITEMS</h3>
|
|
|
|
<p>Want to help? Here's some "to do" items the team has identified as possibly being in scope for Lang. Note that all are still under discussion, so please mail the list before actioning.</p>
|
|
<ul>
|
|
<li>Reflection utilities - work underway in reflect package.</li>
|
|
<li>DateRange/Duration class.</li>
|
|
<li>DurationFormatUtils to be completed and made public.</li>
|
|
<li>CloneUtils - utility class to enable cloning via various different mechanisms. This code exists in [pattern] at present.</li>
|
|
<li>StringUtils.reverseSplit(String, String delim, int count). Should basically be a 'reverseArray(reverseDelimitedString(split(txt, delim, count)))'.</li>
|
|
<li>CharUtils - Utilities to work on a char[] in the same way as a String.</li>
|
|
<li>AStringBuffer - A StringBuffer implementation with additional methods from StringUtils.</li>

|
|
<li>Money and Currency.</li>
|
|
<li>Code examples - Document as many static methods as possible with example usage.</li>
|
