0N/A * An object that implements the <code>RowSetWriter</code> interface,
0N/A * called a <i>writer</i>. A writer may be registered with a <code>RowSet</code>
0N/A * object that supports the reader/writer paradigm.
0N/A * <P>
0N/A * If a disconnected <code>RowSet</code> object modifies some of its data,
0N/A * and it has a writer associated with it, it may be implemented so that it
0N/A * calls on the writer's <code>writeData</code> method internally
0N/A * to write the updates back to the data source. In order to do this, the writer
0N/A * must first establish a connection with the rowset's data source.
0N/A * <P>
0N/A * If the data to be updated has already been changed in the data source, there
0N/A * is a conflict, in which case the writer will not write
0N/A * the changes to the data source. The algorithm the writer uses for preventing
0N/A * or limiting conflicts depends entirely on its implementation.
