    /** Provide an implementation that supports CMP integration with information 
     * required for such support.  This is an interface that a helper class
     * implements that is specific to an application server.
     * 

This interface is subject to change without notice. In particular, * as additional * experience is gained with specific application servers, this interface * may have methods added and removed, even with patch releases. * Therefore, this interface should be considered very volatile, and * any class that implements it might have to be reimplemented whenever * an upgrade to either the application server or internal code occurs.

* The class that implements this interface must register itself * by a static method at class initialization time. For example, *
     * import com.sun.jdo.spi.persistence.support.sqlstore.ejb.*;
     * class blackHerringContainerHelper implements ContainerHelper {
     *    static CMPHelper.register(new blackHerringContainerHelper());
