Interface PathValidator<V,E>

Type Parameters:
V - the graph vertex type
E - the graph edge type
public interface PathValidator<V,E>
Path validator for shortest path algorithms. Shortest path algorithms typically maintain a set of partial paths which are iteratively extended until some stopping criterion is met, e.g. the target vertex is reached. A path validator can be used to enforce additional criteria as to the validity of a given path. A partial path can only be extended by another edge if the path validator deems this extension feasible. As per example, a path validator can be used to enforce that a path connecting a source to a terminal vertex visits at least $n$ vertices.

      boolean isValidPath(GraphPath<V,E> partialPath, E edge)
      Checks if an edge can be added to a previous path element.
      Parameters:
      partialPath - the path from source vertex up to the current vertex.
      edge - the new edge to be added to the path.
      Returns:
      true if edge can be added, false otherwise.
