public abstract class DataSourceProvider
extends Object

A class that provides support for a DataSource.

This interface allows different modules to registers a DataSource through the ServiceLoader. Implementations that are correctly registered will be asked to create a DataSource instance which will be registered into a CompositeDataSource with the given name.

The factory only needs to care about the DataSource creation, and not the rest of the life-cycle.
