Interface ConnectionGenerator

public interface ConnectionGenerator

Used to manage java.sql.Connection objects required by DataJets. The DataJet class can create and manage its own Connection objects, or you can manage them yourself using a ConnectionGenerator. Creating a class that implements ConnectionGenerator allows you to do the following:

• Share the same connection information between several DatJets
• Use a Connection object obtained from a connection pool.
