Class AllEdgesIterable

java.lang.Object

org.janusgraph.graphdb.util.AllEdgesIterable

public class AllEdgesIterable
extends Object

Constructs Iterables over all JanusGraphEdges connecting a provided set of vertices.

Given a set of vertices, one may be interested in all edges that are contained in the subgraph spanned by those vertices.

Method Detail

of

public static Iterable<org.apache.tinkerpop.gremlin.structure.Edge> of(Iterable<? extends org.apache.tinkerpop.gremlin.structure.Vertex> vertices)

Returns an iterable over all edges incident on the vertices returned by the given Iterable over vertices.

Note that this method assumes that the given Iterable will return all vertices in the connected component, otherwise the behavior of this method is undefined.

Parameters:

vertices - Iterable over a set of vertices defining a connected component.

Returns:

Iterable over all edges contained in this component.

of

public static Iterable<org.apache.tinkerpop.gremlin.structure.Edge> of(Set<? extends org.apache.tinkerpop.gremlin.structure.Vertex> vertices)

Returns an iterable over all edges contained in the subgraph spanned by the given vertices.

This method will return all edges whose end points are contained in the given set of vertices.

Parameters:

vertices - Set of vertices

Returns:

All edges contained in the subgraph spanned by the set of vertices.
