Class AbstractValueGraph<N,V>

java.lang.Object

com.google.common.graph.AbstractGraph<N>

com.google.common.graph.AbstractValueGraph<N,V>

Type Parameters:

N - Node parameter type

V - Value parameter type

All Implemented Interfaces:

Graph<N>, ValueGraph<N,V>

@Beta
public abstract class AbstractValueGraph<N,V>
extends AbstractGraph<N>
implements ValueGraph<N,V>

This class provides a skeletal implementation of ValueGraph. It is recommended to extend this class rather than implement ValueGraph directly.

Since:

20.0

Method Details

edgeValue

public V edgeValue(Object nodeU,
 Object nodeV)

Description copied from interface: ValueGraph

If there is an edge connecting nodeU to nodeV, returns the non-null value associated with that edge.

In an undirected graph, this is equal to edgeValue(nodeV, nodeU).

Specified by:

edgeValue in interface ValueGraph<N,V>

toString

public String toString()

Returns a string representation of this graph.

Overrides:

toString in class AbstractGraph<N>
