Class BFS<V,W extends java.lang.Number>

java.lang.Object

berack96.lib.graph.visit.impl.BFS<V,W>

Type Parameters:

V - the vertex of the graph

W - the weight of the graph

All Implemented Interfaces:

VisitStrategy<V,W>

public class BFS<V,W extends java.lang.Number>
extends java.lang.Object
implements VisitStrategy<V,W>

Breadth-first search
The algorithm starts at the root node and explores all of the neighbor nodes at the present depth prior to moving on to the nodes at the next depth level.

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

Description copied from interface: VisitStrategy

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

Specified by:

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

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
