An object that implements the
RowSetWriter
interface,
called a
writer. A writer may be registered with a
RowSet
object 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.
