                V sourceNode,
                V destinationNode)

BaseEdge

public BaseEdge(Graph<V> graph,
                RelationType type,
                String id,
                V sourceNode,
                V destinationNode)

Method Detail

getId

public String getId()

Description copied from interface: Edge

Returns the identifier of this edge. The id must be unique for given graph.

Specified by:

getId in interface Edge<V extends Node<V>>

Returns:

the identifier of this edge

getLabel

public String getLabel()

Description copied from interface: Edge

Returns the label of this edge. The label must not be unique. If the label was not set, it should return an empty string.

Specified by:

getLabel in interface Edge<V extends Node<V>>

Returns:

the label of this edge, or a empty string

setLabel

public void setLabel(String label)

Description copied from interface: Edge

Sets the label of this edge to the given string.

Specified by:

setLabel in interface Edge<V extends Node<V>>

Parameters:

label - the label string, that must not be null

setWeight

public void setWeight(double weight)

getGraph

public Graph<V> getGraph()

Description copied from interface: Edge

Returns the graph where this edge was created.

Specified by:

getGraph in interface Edge<V extends Node<V>>

Returns:

the graph instance

getSource

public V getSource()

Description copied from interface: Edge

Returns the node, that is on the source end of this edge.

Specified by:

getSource in interface Edge<V extends Node<V>>

Returns:

the source node

getDestination

public V getDestination()

Description copied from interface: Edge

Returns the node, that is on the destination end of this edge.

Specified by:

getDestination in interface Edge<V extends Node<V>>

Returns:

the destination node

getWeight

public double getWeight()

Description copied from interface: Edge

Returns the weight of this edge. For standard graph implementations the default should be 1.0, but graph implementations may decide to set another default.

Specified by:

getWeight in interface Edge<V extends Node<V>>

Returns:

the weight of this edge

getType

public RelationType getType()

Description copied from interface: Edge

Returns the RelationType of the edge. If nothing is set, the StandardRelationType.DEFAULT should be returned.

Specified by:

getType in interface Edge<V extends Node<V>>

Returns:

the type of the edge

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:
