Public Member Functions
	GmSparseMatrixTripletData (int lin, int col, double val)
	Constructor.

	GmSparseMatrixTripletData (int ptr, int index, double val, bool)
	Alternate constructor receiving the ptr and the index values.

	GmSparseMatrixTripletData ()
	Dummy constructor to allow using the structure inside a vector.

int	ptr () const
	Returns either the line (CSR) or column (CSC) data depending on the matrix format.

int	index () const
	Returns either the column (CSR) or line (CSC) data depending on the matrix format.

bool	operator< (const GmSparseMatrixTripletData< T > &other) const
	Compare operator to enable sorting with standard sort routines. Not needed by integer sorting. The order is done first by key[1] and then by key[0]. Comparing a single quint64 is much faster than doing up to 3 comparissons if we would treat key[1] and key[2] separetly.

Public Attributes
int	_key [2]
	Either column + line (CSR) or line + column (CSC), depending on the matrix format.

double	_value
	The triplet value.

Detailed Description

Aux structure used when building sparse matrices with the help of a triplet list. The tripet structure stores 2 ints.

a double value. The first int is considered the LEAST significant value when sorting (little-endian architecture).

Templated on the matrix layout type so that we can have specific memory layouts and ptr() / index() implementations for CSR and CSC layouts
