Method Detail

getBaseEdge

public Edge getBaseEdge()

Specified by:

getBaseEdge in interface WrappedEdge<Edge>

vertices

public Iterator<Vertex> vertices(Direction direction)

Description copied from interface: Edge

Retrieve the vertex (or vertices) associated with this edge as defined by the direction. If the direction is Direction.BOTH then the iterator order is: Direction.OUT then Direction.IN.

Specified by:

vertices in interface Edge

Parameters:

direction - Get the incoming vertex, outgoing vertex, or both vertices

Returns:

An iterator with 1 or 2 vertices

properties

public <V> Iterator<Property<V>> properties(String... propertyKeys)

Description copied from interface: Edge

Get an Iterator of properties where the propertyKeys is meant to be a filter on the available keys. If no keys are provide then return all the properties.

Specified by:

properties in interface Edge

Specified by:

properties in interface Element
