| EmbedResultSetMetaData | | public class EmbedResultSetMetaData implements ResultSetMetaData(Code) | | A ResultSetMetaData object can be used to find out about the types
and properties of the columns in a ResultSet.
We take the (cloudscape) ResultDescription and examine it, to return
the appropriate information.
This class can be used outside of this package to convert a
ResultDescription into a ResultSetMetaData object.
