  - getInitialWeight
```
public Weight getInitialWeight()
```
    Description copied from interface: EdgeWeigher
    
    Returns initial weight value (i.e. weight of a "path" starting and terminating in the same vertex; typically 0 value is used).
    
    Specified by:
    
    getInitialWeight in interface EdgeWeigher<TopologyVertex,TopologyEdge>
    
    Returns:
    
    null path weight
  - getNonViableWeight
```
public Weight getNonViableWeight()
```
    Description copied from interface: EdgeWeigher
    
    Returns weight of a link/path that should be skipped (can be considered as an infinite weight).
    
    Specified by:
    
    getNonViableWeight in interface EdgeWeigher<TopologyVertex,TopologyEdge>
    
    Returns:
    
    non viable weight

```
public Weight weight(TopologyEdge edge)
```
    Description copied from interface: EdgeWeigher
    
    Returns the weight of the given edge.
    
    Specified by:
    
    weight in interface EdgeWeigher<TopologyVertex,TopologyEdge>
    
    Parameters:
    
    edge - edge to be weighed
    
    Returns:
