Returns a range of all the browser trackers.

Useful when paginating results. Returns a maximum of end - start instances. start and end are not primary keys, they are indexes in the result set. Thus, 0 refers to the first result in the set. Setting both start and end to QueryUtil.ALL_POS will return the full result set. If orderByComparator is specified, then the query will include the given ORDER BY logic. If orderByComparator is absent and pagination is required (start and end are not QueryUtil.ALL_POS), then the query will include the default ORDER BY logic from BrowserTrackerModelImpl. If both orderByComparator 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.

Specified by:

findAll in interface com.liferay.portal.kernel.service.persistence.BrowserTrackerPersistence

Parameters:

start - the lower bound of the range of browser trackers

end - the upper bound of the range of browser trackers (not inclusive)

Returns:

Returns an ordered range of all the browser trackers.

Useful when paginating results. Returns a maximum of end - start instances. start and end are not primary keys, they are indexes in the result set. Thus, 0 refers to the first result in the set. Setting both start and end to QueryUtil.ALL_POS will return the full result set. If orderByComparator is specified, then the query will include the given ORDER BY logic. If orderByComparator is absent and pagination is required (start and end are not QueryUtil.ALL_POS), then the query will include the default ORDER BY logic from BrowserTrackerModelImpl.

Returns an ordered range of all the browser trackers.

Useful when paginating results. Returns a maximum of end - start instances. start and end are not primary keys, they are indexes in the result set. Thus, 0 refers to the first result in the set.
