public interface RowSetMetaData
An object that contains information about the columns in a
RowSet
object. This interface is
an extension of the ResultSetMetaData
interface with
methods for setting the values in a RowSetMetaData
object.
When a RowSetReader
object reads data into a RowSet
object, it creates a RowSetMetaData
object and initializes it
using the methods in the RowSetMetaData
interface. Then the
reader passes the RowSetMetaData
object to the rowset.
The methods in this interface are invoked internally when an application
calls the method RowSet.execute
; an application
programmer would not use them directly.
