<h3>2. DEPENDENCIES</h3>
|
|
|
|
<p>The <em>Lang</em> component is dependent upon the following external
|
|
components for development and use:</p>
|
|
<ul>
|
|
<li><a href="http://java.sun.com/j2se">Java Development Kit</a>
|
|
(Version 1.2 or later)</li>
|
|
<li><a href="http://www.junit.org">JUnit Testing Framework</a>
|
|
(Version 3.7 or later) - for unit tests only, not required
|
|
for deployment</li>
|
|
</ul>
|
|

<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. 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>Operating system information - maybe part of SystemUtils, maybe another project</li>
|
|
<li>Maths utils - possible addition of mathmatics helper.</li>
|
|
<li>Date and Calendar utils - work underway in time package.</li>
|
|
<li>DateRange</li>
|
|
<li>CloneUtils - utility class to enable cloning via various different mechanisms. This code exists in [pattern] at present.</li>
|
|
<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>
|
|
<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 - [DONE. Test symmetry] </li>
|
|
<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
|
|
<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>
|
|
<li>Money and Currency</li>
|
|
</ul>

<h3>6. COMMITTERS</h3>
|
|
|
|
<p>The following individuals are the primary developers and maintainers of this
|
|
component. Developers who plan to use <em>Lang</em> in their own
|
|
projects are encouraged to collaborate on the future development of this
|
|
component to ensure that it continues to meet a variety of needs.</p>
