Public Member Functions
	GmFixedMeshSetGaussIndex (const GmElementMesh *mesh, const int *cellSet, int numCells, int ruleSet)
	Constructor. The index will include the given cell set if cellSet is not NULL. Otherwise it will span the entire set of mesh cells. The index will only be usable after a call to init()
bool	init ()
	Initializes the index. Returns false on (memory) errors.
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 Attributes
const GmElementMesh *	_mesh
	The mesh object to which this index is tied to.
const int *	_cells
	The cell subset. If NULL the whole mesh will be used.
int	_rule
	The indexed rule set.

Additional Inherited Members

	GmUnfilteredGaussIndexBase ()
	Default empty index constructor.
Protected Attributes inherited from GmUnfilteredGaussIndexBase
int	_numIp
	The fixed number of integartion points per cell or 0 if index based.
int	_numCells
	The number of cells in the index set.

Detailed Description

A Gauss index interface always indexing ALL the elements in either the full mesh or in the given mesh cell list. Once built, the index is fixed.

IMPORTANT: This is NOT a filtered index since when accessing the index methods, the cellId indices, given AND returned, are not really cell indices but indices IN THE CELL SET DOMAIN (either the given cell list or the mesh, when that index becomes a cell index).
