Class QueryResultSet

java.lang.Object

quadbase.util.QueryResultSet

All Implemented Interfaces:

IResultSet, IRow, IRSMetaData

public class QueryResultSet
extends java.lang.Object
implements IResultSet, IRSMetaData

A wrapper around java.sql.ResultSet/ResultSetMetaData to implement IResultSet and IRSMetaData interfaces. This class was implemented later to create a uniform IResultSet interface for data obtained from all sources.
