Method Summary

Modifier and Type	Method and Description
int	clusterCount() Returns the number of SCCs (strongly connected components) in the topology.
long	computeCost() Returns the time, specified in system nanos of how long the topology took to compute.
int	deviceCount() Returns the number of infrastructure devices in the topology.
int	linkCount() Returns the number of infrastructure links in the topology.
int	pathCount() Returns the number of infrastructure paths computed between devices in the topology.
long	time() Returns the time, specified in system nanos of when the topology became available.

Method Detail

time

long time()

Returns the time, specified in system nanos of when the topology became available.

Returns:

time in system nanos

computeCost

long computeCost()

Returns the time, specified in system nanos of how long the topology took to compute.

Returns:

elapsed time in system nanos

clusterCount

int clusterCount()

Returns the number of SCCs (strongly connected components) in the topology.

Returns:

number of clusters

deviceCount

int deviceCount()

Returns the number of infrastructure devices in the topology.

Returns:

number of devices

linkCount

int linkCount()

Returns the number of infrastructure links in the topology.

Returns:

number of links

pathCount

int pathCount()

Returns the number of infrastructure paths computed between devices in the topology. This means the number of all the shortest paths (hop-count) between all device pairs.

Returns:

number of paths
