All Superinterfaces:

ResultSetMetaData, Wrapper

All Known Implementing Classes:

RowSetMetaDataImpl
```
public interface RowSetMetaData
extends ResultSetMetaData
```
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.
