29 ---Purpose: The TopLoc package gives ressources to handle 3D local
30 -- coordinate systems called Locations.
32 -- A Location is a composition of elementary coordinate
33 -- systems, each one is called a Datum. The Location
34 -- keeps track of this composition.
44 pointer TrsfPtr to Trsf from gp;
46 ---Purpose: An elementary 3D coordinate system.
48 private class ItemLocation;
49 ---Purpose: Used to implement the Location. A Datum3D with a
52 private class SListOfItemLocation instantiates
53 SList from TCollection(ItemLocation from TopLoc);
54 ---Purpose: Used to implement the Location.
57 ---Purpose: A Local Coordinate System. A list of elementary
60 class MapLocationHasher instantiates
61 MapHasher from TCollection(Location from TopLoc);
63 class MapOfLocation instantiates
64 Map from TCollection(Location from TopLoc,
65 MapLocationHasher from TopLoc);
67 class IndexedMapOfLocation instantiates
68 IndexedMap from TCollection(Location from TopLoc,
69 MapLocationHasher from TopLoc);
