Interface RowSetMetaData
- All Superinterfaces:
ResultSetMetaData,Wrapper
- All Known Implementing Classes:
RowSetMetaDataImpl
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.
