public interface RowSetWriter
RowSet
to put data updates back to the data source from which the RowSet was
originally populated. An object implementing this interface is called a
writer.
The writer must establish a connection to the RowSet's database
before writing the data. The RowSet calling this interface must
implement the RowSetInternal interface.
The writer may encounter a situation where the updated data needs to be written back to the database, but has already been updated there in the mean time. How a conflict of this kind is handled is determined by the implementation of this writer.
