std::bitset< SIZE >::reference operator[] (std::size_t v)
 Access the bits directly.
 
bool operator[] (std::size_t v) const
 Access the bits directly.
 
bool depends () const
 Checks whether 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 whether 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 whether the edge is one way. I.e. either the influence or the depends flag but is set.
 
bool isTwoWay () const
 Checks whether the edge is two way. I.e. both the influence flag and the depends flag are that.
 
bool isStrong () const
 Checks whether 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 edge in the matrix graph.

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