## Class AbstractDataSource

- java.lang.Object
- - org.springframework.jdbc.datasource.AbstractDataSource

- All Implemented Interfaces:

      public abstract class AbstractDataSource
      extends Object
      implements DataSource

  Abstract base class for Spring's `DataSource` implementations, taking care of the padding.

  'Padding' in the context of this class means default implementations for certain methods from the `DataSource` interface, such as `getLoginTimeout()`, `setLoginTimeout(int)`, and so forth.
