All Superinterfaces:

Highlightable

All Known Implementing Classes:

EdgeImpl

public interface Edge
extends Highlightable

An Edge connects two Vertices.

Method Summary

Vertex	getFirstVertex() Returns one of the Vertices connected by this Edge, referred to as the "first vertex".
String	getLabel() Returns the text to display along the Edge.
Object	getLayoutAttribute() Sets the layout attribute of this Vertex.
Vertex	getOtherVertex(Vertex thisVertex) Given one of the Vertices connected by this Edge, this method returns the other one.
Object	getRenderingAttribute() Returns the rendering attribute of this Vertex.
Vertex	getSecondVertex() Returns one of the Vertices connected by this Edge, referred to as the "second vertex".
float	getWeight() Returns the weight of the Edge.
boolean	isConnected() Returns whether both Vertices are set.
boolean	isConnectedTo(Vertex vertex) Determines whether the specified Vertex is registered as the first or second Vertex of this Edge.
boolean	isDirected() Indicates whether this is a directed or undirected Edge.
void	setLayoutAttribute(Object layoutAttribute) Returns the layout attribute of this Vertex.
void	setRenderingAttribute(Object renderingAttribute) Sets the rendering attribute of this Vertex.

Method Detail

getFirstVertex

Vertex getFirstVertex()

Returns one of the Vertices connected by this Edge, referred to as the "first vertex".

getSecondVertex

Vertex getSecondVertex()

Returns one of the Vertices connected by this Edge, referred to as the "second vertex".

getLabel

String getLabel()

Returns the text to display along the Edge.

isDirected

boolean isDirected()

Indicates whether this is a directed or undirected Edge. When it is directed, the first Vertex is considered to be the source Vertex and the second Vertex is the destination Vertex.

getWeight

float getWeight()

Returns the weight of the Edge. This may influence both graph layout and rendering. Defaults to 1.0.

getLayoutAttribute

Object getLayoutAttribute()

Sets the layout attribute of this Vertex.

setLayoutAttribute

void setLayoutAttribute(Object layoutAttribute)

Returns the layout attribute of this Vertex.

getRenderingAttribute

Object getRenderingAttribute()

Returns the rendering attribute of this Vertex.

setRenderingAttribute

void setRenderingAttribute(Object renderingAttribute)

Sets the rendering attribute of this Vertex.

isConnected

boolean isConnected()

Returns whether both Vertices are set.

isConnectedTo

boolean isConnectedTo(Vertex vertex)

Determines whether the specified Vertex is registered as the first or second Vertex of this Edge.

getOtherVertex

Vertex getOtherVertex(Vertex thisVertex)

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.
