Interface RowSetWriter

public interface RowSetWriter
An interface which provides functionality for a disconnected 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.
