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.

Method Detail

getLabel

java.lang.String getLabel()

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

Returns:

the label of the edge

getFrom

Node getFrom()

Returns:

the source Node

getTo

Node getTo()

Returns:

the destination Node

toString

java.lang.String toString()

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

Overrides:

toString in class java.lang.Object

Returns:

a String representation of the edge

toStringShort

java.lang.String toStringShort()

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

Returns:

a short String representation of the edge

toStringShort

java.lang.String toStringShort(boolean isBackward)

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

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
