Constructor. | |
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.
