| void biu::Graph_UD::addEdge | ( | const size_t | n1, | |
| const size_t | n2 | |||
| ) |
| size_t biu::Graph_UD::connectedComponents | ( | CompLabel & | compID | ) | const |
calculates the number of connected components and writes the nodeID componentID labeling into the given label vector.
- Returns:
- the number of independent connected components
Definition at line 59 of file Graph_UD.cc.
| size_t biu::Graph_UD::degree | ( | const size_t | n | ) | const |
Returns the node degree in the graph.
- Parameters:
-
n node index
- Returns:
- node degree of the node
Definition at line 54 of file Graph_UD.cc.
| size_t biu::Graph_UD::edges | ( | ) | const |
Returns the number of edges in the graph.
- Returns:
- number of edges
Definition at line 45 of file Graph_UD.cc.
| bool biu::Graph_UD::isEdge | ( | const size_t | n1, | |
| const size_t | n2 | |||
| ) |
Tests whether or not an edge in the graph between node n1 and n2.
- Returns:
- true if the edge exists, false otherwise

| void biu::Graph_UD::labelAdjacentNodes | ( | const size_t | curNode, | |
| CompLabel & | compID, | |||
| const size_t | label | |||
| ) | const [protected] |
Labels all uncolored direct or indirect to curNode adjacent nodes and therefore the corresponding conntected component. The compID of uncolored nodes is UINT_MAX. The method is internally called by method 'connectedComponents(..)'.
- Parameters:
-
curNode the initial node to explore the connected component compID the labels set so far label the label of this connected component to set
Definition at line 88 of file Graph_UD.cc.
| size_t biu::Graph_UD::nodes | ( | ) | const |
Returns the number of nodes in the graph.
- Returns:
- number of nodes
Definition at line 40 of file Graph_UD.cc.
| void biu::Graph_UD::printDOT | ( | std::ostream & | out | ) | const |
prints the graph in DOT-format to the given output stream.
Definition at line 137 of file Graph_UD.cc.
| void biu::Graph_UD::remEdge | ( | const size_t | n1, | |
| const size_t | n2 | |||
| ) |
| void biu::Graph_UD::setNodeNumber | ( | const size_t | n | ) |
updates the node list to indices 0..(n-1) and removes all edges previously connected to nodes with index >= n
- Parameters:
-
n the number of nodes after the changes
