Returns the index of the -- element in the structure. is static; GetElement (me : mutable; Index : Integer from Standard) returns Triangle from BRepMesh ---Purpose: Get the value of Element . ---C++: return const & is static; RemoveElement (me : mutable; Index : Integer from Standard) ---Purpose: Removes the element of index in the mesh. is static; SubstituteElement (me : mutable ; Index : Integer from Standard; newElement : Triangle from BRepMesh) ---Purpose: Substitutes the element of index by -- . The links connectivity is updated. returns Boolean from Standard is static; NbElements (me) returns Integer from Standard ---Purpose: Gives the number of elements in this mesh. is static; ClearDomain (me : mutable) ---Purpose: Removes all elements is static; IndexOf (me: mutable; aNode : Vertex from BRepMesh) ---Purpose: Finds the index of the node. Returns 0 if the -- node is not in the mesh. returns Integer from Standard; IndexOf (me; aLink : Edge from BRepMesh) ---Purpose: Finds the index of the Link. Returns 0 if the -- Link is not in the mesh. returns Integer from Standard; IndexOf (me; anElement : Triangle from BRepMesh) ---Purpose: Finds the index of the Element. Returns 0 if -- the Element is not in the mesh. returns Integer from Standard; LinkNeighboursOf (me; theNode : in Integer from Standard) returns ListOfInteger from BRepMesh ---C++: return const & ---Purpose: Gives the list of Link's indices handling the -- node . is static; ElemConnectedTo (me; theLink : in Integer from Standard) returns PairOfIndex from BRepMesh ---C++: return const & ---Purpose: Gives the element's indices conected -- to . is static; ElemOfDomain (me) returns MapOfInteger from BRepMesh ---C++: return const & ---Purpose: Gives the list of element's indices is static; LinkOfDomain (me) returns MapOfInteger from BRepMesh ---C++: return const & ---Purpose: Gives the list of link's indices is static; ClearDeleted (me : mutable) ---Purpose: This method substitute the deleted items by -- the last in Indexed Data Maps to have only -- non-deleted elements, links or nodes in the -- structure. is static; -- Internal methods : ClearElement (me : mutable; Index : Integer from Standard; theElem : Triangle from BRepMesh) ---Purpose: Deletes the element of index in -- the mesh. Used by RemoveElement. is static private; Statistics (me; flot : in out OStream from Standard) ---Purpose: Give informations on map. is static; Allocator (me) returns BaseAllocator from BRepMesh; ---C++: return const& Data (me: mutable) returns VertexTool from BRepMesh; ---Purpose: Give the data structure for cell size and -- tolerance initialization. ---C++: return & fields myNodes : VertexTool from BRepMesh; myLinks : IDMapOfLinkOfDataStructureOfDelaun from BRepMesh; myDelLinks : ListOfInteger from BRepMesh; myElements : IMapOfElementOfDataStructureOfDelaun from BRepMesh; --myDelElements : ListOfInteger from BRepMesh; myElemOfDomain : MapOfInteger from BRepMesh; myLinkOfDomain : MapOfInteger from BRepMesh; myAllocator : BaseAllocator from BRepMesh; end DataStructureOfDelaun;
