public interface Path
extends Link
```
Representation of a contiguous directed path in a network. Path comprises of a sequence of links, where adjacent links must share the same device, meaning that destination of the source of one link must coincide with the destination of the previous link. Path weight (cost) is an aggregation of the weights of the links the path consists of.
