Public Member Functions
	GmMeshGaussIndex (const GmElementMesh *mesh, int ruleSet)
	Constructor. The index will only be usable after a call to init()
bool	init ()
	Initializes the index. Returns false on (memory) errors.
bool	addValues (const int *numAddedValues)
	Adds the given number of cells to the index. Returns false on errors. More...
bool	addValues (int firstAddedElement)
	Similar to addValues(const int*) but getting the types of the added cells from the mesh. Added elements range from firstAddedElement to the last mesh element. The start offset might overlap with existing index range.
void	restoreSize (int oldNumCells)
	Restores the size of the internal index, if necessary, based on the old saved number of cells and integration points.
const GmElementMesh *	mesh () const
	Returns the associated mesh.
Public Member Functions inherited from GmUnfilteredGaussIndexBase
int	numPoints () const
	Returns the number of Gauss points in the index.
int	numCells () const
	Returns the number of cells in the index.
int	numPoints (int cellId) const
	Returns the number of Gauss points for the given Cell.
int	pointIndex (int cellId, int ip) const
	Given a mesh cell index and an integration point index, returns the Gauss point "linear" index, a value between 0 and numPoints()-1.
int	cellIp (int gpIndex, int *ip) const
	Given a Gauss point "linear" index (a value from 0 to numPoints()-1), returns the mesh cell index + its integration point index by filling ip.
void	clear ()
	Clears the index.
size_t	usedMemory () const
	Returns the size of the used memory.

Private Member Functions
bool	addValuesWorker (const int *numAddedValues, int firstAddedElement)
	The work horse for both versions of addValues().
int	numAddedGaussPoints (const int *numTypes, int *pointsPerCell, int *numElem)
int	numAddedGaussPoints (int firstElement, int *pointsPerCell, int *numElem)
int	fixedAddedElements (const int *numTypes, int firstElement, int *numElem) const
	For the added elements set, either specified by a vector with the number of added cells per cell type (mesh addCells() style), or by the actual set of elements in the mesh starting with firstElement when numTypes is NULL, returns the fixed number of integration points per cell in the set if it is homogeneous or 0 if not (or if the set is empty). Also fills numElem (if different from NULL) with the number of elements in the set.
void	fillOffsetVectorFromMesh (int firstCell=0)
	Fills the offset vector with indices given by the current mesh. Assumes that the vector already has the correct size. If firstCell is different from zero, assumes that the ofsset vector for cells with lower index are ok.
void	fillOffsetVectorFromTypes (int firstCell, const int *numTypes, int newFixed)
	Fills the offset vector with indices for the added cells whose types are given by numTypes following the mesh addCells() protocol. Assumes that the vector already has the correct size. If firstCell is different from zero, assumes that the ofsset vector for cells with lower index are ok. If newFixed is different from zero, we know that all numTypes contains a single type with that number of integration points.

Private Attributes
const GmElementMesh *	_mesh
	The mesh object to which this index is tied to.
int	_rule
	The indexed rule set.

Detailed Description

A Gauss index interface always indexing ALL the elements of a mesh, with support for mesh growing.

Member Function Documentation

addValues()

bool GmMeshGaussIndex::addValues

(

const int *

numAddedValues

)

Adds the given number of cells to the index. Returns false on errors.

The numAddedValues parameter should be a list with size equal to GM_NUM_CELL_TYPES, where each entry defines the number of elements of the respective type that will be added to the mesh.

Following the specification in GmCell::addCells(), this function assumes that the new cells where added to the mesh in the order defined by the GmCellType enumeration, i.e, if the numAddedValues list defines that we want 10 new QUAD4 elements and 20 new TRI3 elements, all the QUAD4 elements where added to the mesh before the TRI3 elements since QUAD4 appears before TRI3 in the enumeration.

Important: This function does NOT depend that the new values have been effectivelly added to the mesh, so it can be called before this is effectivelly done in the mesh.
