/**
  * Returns a range of all the proposal rating types.
  *
  * <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 {@link com.liferay.portal.kernel.dao.orm.QueryUtil#ALL_POS}
  * 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 and
  * pagination is required (<code>start</code> and <code>end</code> are not {@link
  * com.liferay.portal.kernel.dao.orm.QueryUtil#ALL_POS}), then the query will include the default
  * ORDER BY logic from {@link com.ext.portlet.model.impl.ProposalRatingTypeModelImpl}. If both
  * <code>orderByComparator</code> and pagination are absent, for performance reasons, the query
  * will not have an ORDER BY clause and the returned result set will be sorted on by the primary
  * key in an ascending order.
  *
  * @param start the lower bound of the range of proposal rating types
  * @param end the upper bound of the range of proposal rating types (not inclusive)
  * @return the range of proposal rating types
  * @throws SystemException if a system exception occurred
