Type Parameters:

V - The Object that represent a vertex

W - The Object that represent the edge (more specifically the weight of the edge)

All Known Subinterfaces:

VisitDistance<V,W>, VisitDistSourceDest<V,W>, VisitSCC<V,W>, VisitTopological<V,W>

All Known Implementing Classes:

BFS, DFS, Dijkstra, Tarjan

public interface VisitStrategy<V,W extends java.lang.Number>

This class is used for define some strategy for the visit of a graph.

Method Summary

Modifier and Type	Method and Description
VisitInfo<V>	visit(Graph<V,W> graph, V source, java.util.function.Consumer<V> visit) With this the graph will be visited accordingly to the strategy of the visit. Some strategy can accept a source vertex null, because they visit all the graph anyway. If you want to stop the visit of the graph, you just have to throw any exception in the visit function, but be sure to catch it

Method Detail

visit

VisitInfo<V> visit(Graph<V,W> graph,
                   V source,
                   java.util.function.Consumer<V> visit)
            throws java.lang.NullPointerException,
                   java.lang.IllegalArgumentException,
                   java.lang.UnsupportedOperationException

With this the graph will be visited accordingly to the strategy of the visit.
Some strategy can accept a source vertex null, because they visit all the graph anyway.
If you want to stop the visit of the graph, you just have to throw any exception in the visit function, but be sure to catch it

Parameters:

graph - the graph to visit

source - the source of the visit

visit - the function to apply at each vertex when they are visited

Returns:

an info of the view

Throws:

java.lang.NullPointerException - if one of the arguments is null (only the consumers can be null)

java.lang.IllegalArgumentException - if the source vertex is not in the graph

java.lang.UnsupportedOperationException - in the case that the visit algorithm cannot be applied to the graph
