implements <a href="../../../../org/apache/commons/beanutils/DynaClass.html" title="interface in org.apache.commons.beanutils">DynaClass</a></pre>
<div class="block"><p>Implementation of <code>DynaClass</code> for DynaBeans that wrap the
<code>java.sql.Row</code> objects of a <code>java.sql.ResultSet</code>.
The normal usage pattern is something like:</p>
<pre>
ResultSet rs = ...;
ResultSetDynaClass rsdc = new ResultSetDynaClass(rs);
Iterator rows = rsdc.iterator();
while (rows.hasNext()) {
DynaBean row = (DynaBean) rows.next();
... process this row ...
}
rs.close();
</pre>
<p>Each column in the result set will be represented as a DynaBean
property of the corresponding name (optionally forced to lower case
for portability).</p>
<p><strong>WARNING</strong> - Any <a href="../../../../org/apache/commons/beanutils/DynaBean.html" title="interface in org.apache.commons.beanutils"><code>DynaBean</code></a> instance returned by
this class, or from the <code>Iterator</code> returned by the
<code>iterator()</code> method, is directly linked to the row that the
underlying result set is currently positioned at. This has the following
implications:</p>
<ul>
<li>Once you retrieve a different <a href="../../../../org/apache/commons/beanutils/DynaBean.html" title="interface in org.apache.commons.beanutils"><code>DynaBean</code></a> instance, you should
no longer use any previous instance.</li>
<li>Changing the position of the underlying result set will change the
data that the <a href="../../../../org/apache/commons/beanutils/DynaBean.html" title="interface in org.apache.commons.beanutils"><code>DynaBean</code></a> references.</li>
<li>Once the underlying result set is closed, the <a href="../../../../org/apache/commons/beanutils/DynaBean.html" title="interface in org.apache.commons.beanutils"><code>DynaBean</code></a>
instance may no longer be used.</li>
</ul>
<p>Any database data that you wish to utilize outside the context of the
current row of an open result set must be copied. For example, you could
use the following code to create standalone copies of the information in
a result set:</p>
<pre>
ArrayList results = new ArrayList(); // To hold copied list
ResultSetDynaClass rsdc = ...;
DynaProperty[] properties = rsdc.getDynaProperties();
BasicDynaClass bdc =
new BasicDynaClass("foo", BasicDynaBean.class,
rsdc.getDynaProperties());
Iterator rows = rsdc.iterator();
while (rows.hasNext()) {
DynaBean oldRow = (DynaBean) rows.next();
DynaBean newRow = bdc.newInstance();
PropertyUtils.copyProperties(newRow, oldRow);
results.add(newRow);
}
</pre></div>
