getDistance(V source,
V target)
Returns the distance from the
source vertex to the
target vertex. |
Map<V,Number> |
getDistanceMap(V source)
Returns a
Map which maps each vertex in the graph (including
the source vertex) to its distance (represented as a Number)
from source . |
Number getDistance(V source, V target)
source
vertex to the
target
vertex. If target
is not reachable from
source
, returns null.source

Map<V,Number> getDistanceMap(V source)
Map
which maps each vertex in the graph (including
the source
vertex) to its distance (represented as a Number)
from source
. If any vertex is not reachable from
source
, no distance is stored for that vertex.source
