public class DelegatingDataSource
extends java.lang.Object
implements javax.sql.DataSource
DataSource
implementation that delegates all calls
to a given target DataSource
.
This class is meant to be subclassed, with subclasses overriding only
those methods (such as getConnection()
) that should not simply
delegate to the target DataSource.
