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 data source before writing the data. The RowSet calling this interface must implement the RowSetInternal interface.

The Writer may encounter a situation where the updated data being written back to the data source has already been updated in the data source. How a conflict of this kind is handled is determined by the implementation of the Writer.
