org.apache.derby.impl.sql.execute
Class GenericResultSetFactory
java.lang.Objectorg.apache.derby.impl.sql.execute.GenericResultSetFactory
- All Implemented Interfaces:
- org.apache.derby.iapi.sql.execute.ResultSetFactory
- public class GenericResultSetFactory
- extends java.lang.Object
- implements org.apache.derby.iapi.sql.execute.ResultSetFactory
- extends java.lang.Object
ResultSetFactory provides a wrapper around all of the result sets used in this execution implementation. This removes the need of generated classes to do a new and of the generator to know about all of the result sets. Both simply know about this interface to getting them.
In terms of modularizing, we can create just an interface to this class and invoke the interface. Different implementations would get the same information provided but could potentially massage/ignore it in different ways to satisfy their implementations. The practicality of this is to be seen.
The cost of this type of factory is that once you touch it, you touch *all* of the possible result sets, not just the ones you need. So the first time you touch it could be painful ... that might be a problem for execution.
