Method Detail

checkEclipseLinkCache

public static java.lang.Object checkEclipseLinkCache(DatabaseQuery query,
                                                     Record record,
                                                     Session session)

This method will cause EclipseLink to check the EclipseLink cache for the object. EclipseLink always checks the shared cache before executing a query but because the query has been redirected in this case the cache check has also been redirected. Through this method the redirector can have EclipseLink check the cache in the normal manner.
