ext.ojalgo.pride.PersistenceProvider

public abstract class PersistenceProvider
extends Object

This class acts as a facade to PriDE. The other classes in this project do NOT access PriDE directly. Everything is accessed through this class.

• None of the methods here should handle the SQLException exception.
• Methods that modify the database returns an integer with the number of modified objects.
• Methods that query the database return an EntityBean or a collection of them.
