virtual void	edgeAdjacentCells (const GmCell cell, int edgeIndex, QVector< GmCell > &list) const =0
	Fills list with all the cells that include the given edge, idetntified by a cell + local edge index pair. The input cell is added to the list. In 2D this is simillar to calling adjacentCell()

	Overload for edgeAdjacentCells(const GmCell, int, QVector<GmCell>&) filling a list of const pointers.

virtual bool	isBorderNode (int nodeIndex) const =0
	Returns true if this node belongs to an edge/face that does not have an adjacent cell. Returns false otherwise (this includes "nodes belonging only to "strange" elements or not belonging to a cell at all).

virtual void	printParameters (const GmLogCategory &logger, GmLogLevel level) const =0
	Prints a summary of the topological structure in a way to be integrated with the mesh printed by GmCellMesh::printParameters()

virtual void	print (const GmLogCategory &logger, GmLogLevel level) const =0
	Prints the topological structure FULL information to the specified logger/level.

virtual size_t	printMemoryStatistics (const GmLogCategory &logger, GmLogLevel level) const =0
	Prints memory usage for the topological data structure to the given logger. Returns the used memory as reported by usedMemory()

virtual size_t	usedMemory () const =0
	Returns the approximate memory used for storing the topological data structure.

Detailed Description

Base interface class for mesh topological queries.

Member Enumeration Documentation

◆ QueryOptions

enum GmCellMeshTopology::QueryOptions

Query options for adjacent nodes retrieval.

Enumerator
QSTAR	Returns the set of connected nodes, ignoring quadratic nodes.

Member Function Documentation

◆ adjacentCell()

virtual GmCell* GmCellMeshTopology::adjacentCell	(	const GmCell *	cell,
		int	sideIndex,
		int *	adjSideIndex = `NULL`
	)		const

pure virtual

Given a cell, returns the adjacent cell sharing the given side, represented by a cell edge index for surface meshes or by a cell face index for solid mehses.

The sideIndex is a value between 0 and the number of element edges/face - 1, defining the position of the edge/face of interest in the cell. Returns NULL if the edge/face belongs to the mesh boundary. Also returns NULL for "strange" elements that don't have topology information (non-manifold elements like bars for a surface mesh and bars, quads and triangles for solid meshes).

If adjSideIndex is different from NULL, it will be filled with the side index of the adjacent edge/face in the adjacent cell.

◆ nodeAdjacentNodes()

virtual void GmCellMeshTopology::nodeAdjacentNodes	(	int	nodeIndex,
		QueryOptions	options,
		QVector< int > &	list
	)		const

pure virtual

Fills list with the set of adjacent nodes to the given node. The result list depends on the given options parameter.

1—10-—2—11-—3 nodeIndex = 5: | | | options = STAR - Returns {2, 4, 8, 6} 12 22 13 23 14 options = QSTAR - Returns {13, 15, 18, 16} | | | 4—15-—5—16-—6 nodeIndex = 15: | | | options = STAR or QSTAR - Returns {4, 5} 17 24 18 25 19 | | | nodeIndex = 22: 7—20-—8—21-—9 options = STAR or QSTART - Returns {}
