<div><p>You can request certain properties to be satisfied by the rowsets.
|
||
|
|
Common properties include the set of interfaces to be supported by the resulting
|
||
|
|
rowset.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">RowSets are ResultSets</h4><p>The RowSet interface extends
|
||
|
|
the ResultSet interface which means that RowSets have the ability to perform
|
||
|
|
all the functions that ResultSets can do. For example, RowSets can be scrollable
|
||
|
|
and updateable.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">RowSets can be disconnected from the database</h4><p>There
|
||
|
|
are two categories of RowSets:</p>
|
||
|
|
<ul><li><strong>Connected</strong> While connected RowSets are populated with data, they
|
||
|
|
always have internal connections to the underlying database open and serve
|
||
|
|
as wrappers around a ResultSet implementation.</li>
|
||
|
|
<li><strong>Disconnected</strong> Disconnected RowSets are not required to maintain
|
||
|
|
connections to their data source at all times. Disconnected RowSets can be
|
||
|
|
detached from the database, be used in a variety of ways, and then be reconnected
|
||
|
|
to the database to mirror any changes made to them.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">RowSets are JavaBeans™ components</h4><p>RowSets
|
||
|
|
have support for event handling based on the JavaBeans event-handling model. They
|
||
|
|
also have properties that can be set. These properties can be used by the
|
||
|
|
RowSet to perform the following:</p>
|
||
|
|
<ul><li>Establish a connection to the database.</li>
|
||
|
|
<li>Process an SQL statement.</li>
|
||
|
|
<li>Determine features of the data that the RowSet represents and handle other
|
||
|
|
internal features of the RowSet object.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">RowSets are serializable</h4><p>RowSets can be serialized
|
||
|
|
and deserialized to allow them to flow over a network connection, be written
|
||
|
|
out to a flat file (that is, a text document without any word processing or
|
||
|
|
other structure characters), and so on. </p>

Unlike some of the better-known interfaces of the JDBC specification, the RowSet specification is designed to be more of a framework than an actual implementation. The RowSet interfaces define a set of core functionality that all RowSets have. RowSet implementation providers have considerable freedom to define the functionality that is needed to fit their needs in a specific problem space.">RowSets</a></div>

Its implementation adheres closely to the description of a CachedRowSet. The DB2CachedRowSet is a container for rows of data from a ResultSet.
