Constructor Detail

Edge

public Edge()

Create a new Edge with initially no connected Vertices.

Edge

public Edge(Vertex source,
            Vertex destination)

Create a new Edge connecting the specified Vertices.

Method Detail

getSource

public Vertex getSource()

setSource

public void setSource(Vertex source)

getDestination

public Vertex getDestination()

setDestination

public void setDestination(Vertex destination)

getLayoutAttribute

public Object getLayoutAttribute()

setLayoutAttribute

public void setLayoutAttribute(Object layoutAttribute)

isConnectedTo

public boolean isConnectedTo(Vertex vertex)

Determines whether the specified Vertex is connected to this Edge.

connects

public boolean connects(Vertex vertex1,
                        Vertex vertex2)

Determines whether this Edge connects the two specified Vertices.

getOtherVertex

public Vertex getOtherVertex(Vertex vertex)

Given one of the Vertices connected by this Edge, this method returns the other one. When the specified Vertex is not connected to this Edge (according to the registration of the Edge itself), 'null' is returned.
