Interface RowSetMetaData

All Superinterfaces:: ResultSetMetaData

public interface RowSetMetaData
extends ResultSetMetaData

The RowSetMetaData interface extends ResultSetMetaData with methods that allow a metadata object to be initialized. A RowSetReader may create a RowSetMetaData and pass it to a rowset when new data is read.
