- Method Detail
  - distance
```
double distance(V source,
                V target)
```
    Get the distance of the shortest path between two vertices.
    
    Parameters:
    
    source - the source vertex
    
    target - the target vertex
    
    Returns:
    
    the sum of weights of edges in the shortest path from the source to target, or Double.POSITIVE_INFINITY if no such path exists
    
    Throws:
    
    NoSuchVertexException - if source or target are not vertices in the graph
    
    IllegalArgumentException - if the shortest paths were computed on pairs of vertices from a subset of the vertices of the graph (rather than all pairs), and source or target are not in the subset
  - getPath
```
Path<V,E> getPath(V source,
                        V target)
```
    Get the shortest path between vertices.
    
    Parameters:
    
    source - the source vertex
    
    target - the target vertex
    
    Returns:
    
    the shortest path from the source to target, or null if no such path exists
    
    Throws:
    
    NoSuchVertexException - if source or target are not vertices in the graph
    
    IllegalArgumentException - if the shortest paths were computed on pairs of vertices from a subset of the vertices of the graph (rather than all pairs), and source or target are not in the subset
