Parametrize DerbyTable classes with Tuple generic types #233

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Currently, DerbyTable classes are too generic because they are not associated 
with a tuple storage/DB schema type. It would help if each DerbyTable class had 
a generic parameter that specified the kind of Tuple the table contains. This 
would also help our design by keeping tuple/schema information in a single 
object, which we can then operate on.

For this task, first create an abstract Tuple class. This class will maintain a 
reference to a DerbyTable, and maybe a few other things later on.

Next, subclass Tuple to create a class for every DerbyTable, e.g., 
VisitorTuple. Each Tuple subclass should contain data members that represent an 
actual DB tuple.

Finally, parametrize all existing DerbyTable classes with the corresponding 
Tuple types.
