public class DatabaseTransactionFactory

extends java.lang.Object

The factory for creating DBTransaction instances.

This class is used by the framework to create an instance when the client attempts to establish a connection to the database. Applications may provide custom DBTransaction implementations. Such applications will need to subclass this class and DBTransactionImpl.

The framework calls the getFactory() method to get the currently installed factory, and calls its create() method to establish a connection.

This class has a single active instance, which cannot be replaced.

JDevloper 3.0
