the class FooPersistenceImpl method findByUuid.

/**
 * Returns an ordered range of all the foos where uuid = ?.

 * <p>
 * Useful when paginating results. Returns a maximum of <code>end - start</code> instances. <code>start</code> and <code>end</code> are not primary keys, they are indexes in the result set. Thus, <code>0</code> refers to the first result in the set. Setting both <code>start</code> and <code>end</code> to <code>QueryUtil#ALL_POS</code> will return the full result set. If <code>orderByComparator</code> is specified, then the query will include the given ORDER BY logic. If <code>orderByComparator</code> is absent, then the query will include the default ORDER BY logic from <code>FooModelImpl</code>.
 * </p>
 *
 * @param uuid the uuid
 * @param start the lower bound of the range of foos
 * @param end the upper bound of the range of foos (not inclusive)
 * @param orderByComparator the comparator to order the results by (optionally <code>null</code>)
 * @param useFinderCache whether to use the finder cache
 * @return the ordered range of matching foos
