Method Detail

initFromGraph

void initFromGraph()

close

void close()

calculatePriority

float calculatePriority(int node)

Calculates the priority of a node without changing the graph. Lower (!!) priority nodes are contracted first.

contractNode

com.carrotsearch.hppc.IntContainer contractNode(int node)

Adds the required shortcuts for the given node.

Returns:

the set of nodes adjacent to this node (before contraction)

finishContraction

void finishContraction()

getAddedShortcutsCount

long getAddedShortcutsCount()

getStatisticsString

String getStatisticsString()

getDijkstraCount

long getDijkstraCount()

getDijkstraSeconds

float getDijkstraSeconds()

prepareContraction

void prepareContraction()
