VTIEnvironment

Does anyone know the purpose of the following class: 
org.apache.derby.vti.VTIEnvironment? This is the type of the argument to 
the VTICosting methods. However, these objects are never inspected by 
any of the classes which implement VTICosting. The Cloudscape 3.5 
documentation says, "The methods take a parameter of type 
COM.cloudscape.database.VTIEnvironment, which you can ignore for the 
current release."

Thanks,
-Rick

Rick, just wanted to say that I searched the code for VTIEnvironment and
found that VTIResultSet implements the interface VTIEnvironment and those
methos from VTIEnvironment are used by some other classes. But you are
right, I don't see VTICosting using the VTIEnvironment argument at all.

So, I am not sure of the purpose of VTIEnvironment but it is being
implemented by VTIResultSet class.
