Constructor Detail

DefaultPath

public DefaultPath(List<E> edges,
                   Weight cost)

Creates a new path from the specified list of edges and cost.

Parameters:

edges - list of path edges

cost - path cost as a weight object

Method Detail

src

public V src()

Description copied from interface: Edge

Returns the edge source vertex.

Specified by:

src in interface Edge<V extends Vertex>

Returns:

source vertex

dst

public V dst()

Description copied from interface: Edge

Returns the edge destination vertex.

Specified by:

dst in interface Edge<V extends Vertex>

Returns:

destination vertex

cost

public Weight cost()

Description copied from interface: Path

Returns the total cost of the path as a weight object.

Specified by:

cost in interface Path<V extends Vertex,E extends Edge<V>>

Returns:

path cost as a weight object

edges

public List<E> edges()

Description copied from interface: Path

Returns the list of edges comprising the path. Adjacent edges will share the same vertex, meaning that a source of one edge, will be the same as the destination of the prior edge.

Specified by:

edges in interface Path<V extends Vertex,E extends Edge<V>>

Returns:

list of path edges

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
