Constructor Summary

SimpleEdge(Node fromNode, Node toNode, java.lang.String edgeLabel)
Constructs a new edge.

Method Summary

Node	getFrom()
java.lang.String	getLabel() If in need of a readable rendition of the edge's features, use the toString functions.
Node	getTo()
java.lang.String	toString() Constructs a full representation of the edge, including its two adjacent nodes.
java.lang.String	toStringShort() Constructs a short representation of the edge, including only information about label.
java.lang.String	toStringShort(boolean isBackward) Constructs a short representation of the edge, including only information about label and direction.

Field Detail

label

protected java.lang.String label

The label of the edge.

from

protected Node from

The source of the edge.

to

protected Node to

The destination of the edge.

Constructor Detail

SimpleEdge

public SimpleEdge(Node fromNode,
                  Node toNode,
                  java.lang.String edgeLabel)

Constructs a new edge.

Parameters:

fromNode - : the source Node; the edge is added to the node's outEdges list.

toNode - : the destination Node; the edge is added to the node's inEdges list.

edgeLabel - : the label of the edge.

Method Detail

getLabel

public java.lang.String getLabel()

Description copied from interface: Edge

If in need of a readable rendition of the edge's features, use the toString functions.

Specified by:

getLabel in interface Edge

Returns:

the label of the edge

getFrom

public Node getFrom()

Specified by:

getFrom in interface Edge

Returns:

the source Node

getTo

public Node getTo()

Specified by:

getTo in interface Edge

Returns:

the destination Node

toString

public java.lang.String toString()

Description copied from interface: Edge

Constructs a full representation of the edge, including its two adjacent nodes.

Specified by:

toString in interface Edge

Overrides:

toString in class java.lang.Object

Returns:

a String representation of the edge

toStringShort

public java.lang.String toStringShort()

Description copied from interface: Edge

Constructs a short representation of the edge, including only information about label.

Specified by:

toStringShort in interface Edge

Returns:

a short String representation of the edge

toStringShort

public java.lang.String toStringShort(boolean isBackward)

Description copied from interface: Edge

Constructs a short representation of the edge, including only information about label and direction. The direction depends on the general direction of the representation.

Specified by:

toStringShort in interface Edge

Parameters:

isBackward - - mentions that the edge is in opposite direction with respect to the representation and should be represented accordingly

Returns:

a short String representation of the edge
