getVertices

public static java.util.Set<Vertex> getVertices(Vertex vertex,
                                                java.util.function.Function<Vertex,java.util.Collection<Vertex>> nextVertices,
                                                java.util.function.Function<Vertex,java.lang.Boolean> stoppingCondition,
                                                java.util.function.Predicate<Vertex> shouldAdd)

getVertices

public static java.util.Set<Vertex> getVertices(java.util.List<Vertex> vertices,
                                                java.util.function.Function<Vertex,java.util.Collection<Vertex>> nextVertices,
                                                java.util.function.Function<Vertex,java.lang.Boolean> stoppingCondition,
                                                java.util.function.Predicate<Vertex> shouldAdd)

Parameters:

vertices - vertices to start propagation from

nextVertices - The next vertices to move to given a current vertex. E.g getChildren for downstream or getParents for upstream.

shouldAdd - true when a given vertex should be included in the result, false otherwise

stoppingCondition - true when a given vertex should be stopped at

Returns:

A Set of vertices that are in the direction implied by nextVertices and filtered by shouldAdd
