Class GlobalClusteringCoefficient<K extends Comparable<K> & org.apache.flink.types.CopyableValue<K>,VV,EV>

java.lang.Object

org.apache.flink.graph.GraphAnalyticBase<K,VV,EV,GlobalClusteringCoefficient.Result>

org.apache.flink.graph.library.clustering.undirected.GlobalClusteringCoefficient<K,VV,EV>

Type Parameters:

K - graph ID type

VV - vertex value type

EV - edge value type

All Implemented Interfaces:

GraphAnalytic<K,VV,EV,GlobalClusteringCoefficient.Result>

public class GlobalClusteringCoefficient<K extends Comparable<K> & org.apache.flink.types.CopyableValue<K>,VV,EV>
extends GraphAnalyticBase<K,VV,EV,GlobalClusteringCoefficient.Result>

The global clustering coefficient measures the connectedness of a graph. Scores range from 0.0 (no triangles) to 1.0 (complete graph).

Method Detail

run

public GlobalClusteringCoefficient<K,VV,EV> run(Graph<K,VV,EV> input)
                                         throws Exception

Description copied from interface: GraphAnalytic

All GraphAnalytic processing must be terminated by an OutputFormat. Rather than obtained via accumulators rather than returned by a DataSet.

Specified by:

run in interface GraphAnalytic<K extends Comparable<K> & org.apache.flink.types.CopyableValue<K>,VV,EV,GlobalClusteringCoefficient.Result>

Overrides:

run in class GraphAnalyticBase<K extends Comparable<K> & org.apache.flink.types.CopyableValue<K>,VV,EV,GlobalClusteringCoefficient.Result>

Parameters:

input - input graph

Returns:

this

Throws:

Exception

getResult

public GlobalClusteringCoefficient.Result getResult()

Description copied from interface: GraphAnalytic

This method must be called after the program has executed. 1) "run" analytics and algorithms 2) call ExecutionEnvironment.execute() 3) get analytic results

Returns:

the result
