Class DbQueryManagerFactory

rife.database.DbQueryManagerFactory

Direct Known Subclasses:

DatabaseResourcesFactory

public abstract class DbQueryManagerFactory
extends Object

This class allows for DbQueryManagers to be created more dynamically and with more features than by direct instantiation.

By using the DbQueryManagerFactory, DbQueryManager child classes can have custom methods that are implemented by different "drivers", based on the database software behind the Datasource. Database "drivers" are looked up through the manager's classpath according to the package name and the encoded class name of the JDBC driver (dots are replaced by underscores). The default, or "generic" driver, must be created under this package and will be used when no specific driver can be found for a particular Datasource. All the created DbQueryManagers are cached in the provided cache and are re-used on successive calls rather than being re-instantiated.
