DtTerrainSourcePager is the base class for terrain pagers. There will be one terrainSourcePager per terrain patch. They will each handle paging in terrain from an individual source, such as metaflight, paged .ive, or osgEarth streaming terrain.

virtual

Takes incoming commands off the command queue and adds them to the priority-sorted command map.

DtPagerCommandQueue DtTerrainSourcePager::myCommandQueue

Thread-safe queue to put commands on.

DtCommandPriorityMultimap DtTerrainSourcePager::myPriorityCommandMultimap

Multimap of priorities to paging commands. Commands are taken off the queue and put here until they are either executed or expired.
