Description	Like all `OsidLists` , `ObstacleEnablerList` provides a means for accessing `ObstacleEnabler` elements sequentially either one at a time or many at a time. Examples: while (oel.hasNext()) { ObstacleEnabler enabler = oel.getNextObstacleEnabler(); } or while (oel.hasNext()) { ObstacleEnabler[] enablers = oel.getNextObstacleEnablers(oel.available()); }
Method	getNextObstacleEnabler
Description	Gets the next `ObstacleEnabler` in this list.
