Method Detail

getSource

public DirectedVertex<T> getSource()

Gets the source vertex of this edge

Returns:

the source vertex

getTarget

public DirectedVertex<T> getTarget()

Gets the target vertex of this edge

Returns:

the target vertex

removeFromGraph

public void removeFromGraph()

Description copied from class: GraphComponent

Removes this component from the graph it is a part of. When extending this class this method will probably need to be overridden and called with super;

Overrides:

removeFromGraph in class GraphComponent

reverse

public void reverse()

Reverses the direction of this edge

setSource

public void setSource(Vertex<T> source)

Sets a different vertex to be the source for this edge

Parameters:

source - the new source

setTarget

public void setTarget(Vertex<T> target)

Sets a different vertex to be the target for this edge

Parameters:

target - the new target

toString

public java.lang.String toString()

Overrides:

toString in class GraphComponent
