/**
 * This interface is to be implemented by a JPA vendor to provide extensions to
 * JPA UI functionality. This is intended to work in conjunction with a core
 * {@link JpaPlatform JPA platform} implementation with the same ID.
 * <p>
 * Any implementation's state should be <em>static</em>.
 * <p>
 * The "generic" extension supplies UI for the core platform extension with the same
 * ID.
 * <p>
 * See the extension point: <code>org.eclipse.jpt.jpa.ui.jpaPlatform</code>
 * <p>
 * To retrieve the JPA UI platform corresponding to a JPA platform:
 * <pre>
 * JpaProject jpaProject = ...;
 * JpaPlatform jpaPlatform = jpaProject.getJpaPlatform();
 * JpaPlatformUi jpaPlatformUi = (JpaPlatformUi) jpaPlatform.getAdapter(JpaPlatformUi.class);
 * </pre>
 * Provisional API: This interface is part of an interim API that is still
 * under development and expected to change significantly before reaching
 * stability. It is available at this early stage to solicit feedback from
 * pioneering adopters on the understanding that any code that uses this API
 * will almost certainly be broken (repeatedly) as the API evolves.
