All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`Weight`	`getInitialWeight()`	Returns initial weight value (i.e.
`Weight`	`getNonViableWeight()`	Returns weight of a link/path that should be skipped (can be considered as an infinite weight).

- Method Detail
  - weight
```
Weight weight(E edge)
```
    Returns the weight of the given edge.
    
    Parameters:
    
    edge - edge to be weighed
    
    Returns:
    
    edge weight
  - getInitialWeight
```
Weight getInitialWeight()
```
    Returns initial weight value (i.e. weight of a "path" starting and terminating in the same vertex; typically 0 value is used).
    
    Returns:
    
    null path weight
  - getNonViableWeight
```
Weight getNonViableWeight()
```
    Returns weight of a link/path that should be skipped (can be considered as an infinite weight).
    
    Returns:
    
    non viable weight
