 * An object that implements the <code>RowSetWriter</code> interface,

 * object that supports the reader/writer paradigm.
 * <P>
 * If a disconnected <code>RowSet</code> object modifies some of its data,
 * and it has a writer associated with it, it may be implemented so that it
 * calls on the writer's <code>writeData</code> method internally
 * to write the updates back to the data source. In order to do this, the writer
 * must first establish a connection with the rowset's data source.
 * <P>
 * If the data to be updated has already been changed in the data source, there
 * is a conflict, in which case the writer will not write
 * the changes to the data source.  The algorithm the writer uses for preventing
 * or limiting conflicts depends entirely on its implementation.
