/**
 * 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
 * JPA platform ({@link JpaPlatform}) implementation with the same ID.
 * <p>
 * Any implementation should be <em>stateless</em> in nature.
 * <p>
 * The "generic" extension supplies UI for the core platform extension with the same
 * ID.
 *
 * See the extension point: org.eclipse.jpt.jpa.ui.jpaPlatform
 *
 * 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.
