Public Types
enum
	Flags of the link.

Public Member Functions
	EdgeProperties ()
	Constructor.
std::bitset< SIZE >::reference	operator[] (std::size_t v)
	Access the bits directly.
bool	operator[] (std::size_t v) const
	Acess the bits directly.
bool	depends () const
	Checks wether the vertex the edge points to depends on the vertex the edge starts. More...
void	setDepends ()
	Marks the edge as one of which the end point depends on the starting point.
void	resetDepends ()
	Resets the depends flag.
bool	influences () const
	Checks wether the start vertex is influenced by the end vertex. More...
void	setInfluences ()
	Marks the edge as one of which the start vertex by the end vertex.
void	resetInfluences ()
	Resets the influence flag.
bool	isOneWay () const
	Checks wether the edge is one way. I.e. either the influence or the depends flag but is set.
bool	isTwoWay () const
	Checks wether the edge is two way. I.e. both the influence flag and the depends flag are that.
bool	isStrong () const
	Checks wether the edge is strong. I.e. the influence or depends flag is set.
void	reset ()
	Reset all flags.
void	printFlags () const
	Prints the attributes of the edge for debugging.

Detailed Description

Class representing the properties of an ede in the matrix graph.

During the coarsening process the matrix graph needs to hold different properties of its edges. This class ontains methods for getting and setting these edge attributes.
