com.tinkerpop.blueprints.util.wrappers.event.EventElement

com.tinkerpop.blueprints.util.wrappers.event.EventVertex

All Implemented Interfaces:

Element, Vertex

public class EventVertex
extends EventElement
implements Vertex

Method Detail

getEdges

public Iterable<Edge> getEdges(Direction direction,
                      String... labels)

Description copied from interface: Vertex

Return the edges incident to the vertex according to the provided direction and edge labels.

Specified by:

getEdges in interface Vertex

Parameters:

direction - the direction of the edges to retrieve

labels - the labels of the edges to retrieve

Returns:

an iterable of incident edges

getVertices

public Iterable<Vertex> getVertices(Direction direction,
                           String... labels)

Description copied from interface: Vertex

Return the vertices adjacent to the vertex according to the provided direction and edge labels. This method does not remove duplicate vertices (i.e. those vertices that are connected by more than one edge).

Specified by:

getVertices in interface Vertex

Parameters:

direction - the direction of the edges of the adjacent vertices

labels - the labels of the edges of the adjacent vertices

Returns:

an iterable of adjacent vertices

query

public VertexQuery query()

Description copied from interface: Vertex

Generate a query object that can be used to fine tune which edges/vertices are retrieved that are incident/adjacent to this vertex.

Specified by:

query in interface Vertex

Returns:

a vertex query object with methods for constraining which data is pulled from the underlying graph

addEdge

public Edge addEdge(String label,
           Vertex vertex)

Description copied from interface: Vertex

Add a new outgoing edge from this vertex to the parameter vertex with provided edge label.

Specified by:

addEdge in interface Vertex

Parameters:

label - the label of the edge

vertex - the vertex to connect to with an incoming edge

Returns:

the newly created edge

getBaseVertex

public Vertex getBaseVertex()
