public interface RowSetWriter
RowSetWriterinterface, called a writer. A writer may be registered with a
RowSetobject that supports the reader/writer paradigm.
If a disconnected
RowSet 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
writeData 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.
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.
Writes the changes in this
RowSetWriterobject's rowset back to the data source from which it got its data.

RowSetInternalinterface, (2) with which this writer is registered, and (3) that called this method internally
