serac::SignedIndex Struct Reference

this type explicitly stores sign (typically used conveying edge/face orientation) and index values More...

#include <dof_numbering.hpp>

Public Member Functions
	operator uint32_t ()
	the implicit conversion to int extracts only the index

Public Attributes
uint32_t	index_
	the actual index of some quantity
int	sign_
	whether or not the value associated with this index is positive or negative

Detailed Description

this type explicitly stores sign (typically used conveying edge/face orientation) and index values

TODO: investigate implementation via bitfield (should have smaller memory footprint, better readability than mfem's {sign, index} int32_t encoding)
