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

java.lang.Object

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

org.apache.flink.graph.library.clustering.directed.TriadicCensus<K,VV,EV>

Type Parameters:

K - graph ID type

VV - vertex value type

EV - edge value type

All Implemented Interfaces:

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

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

A triad is formed by three connected or unconnected vertices in a graph. The triadic census counts the occurrences of each type of triad.

Method Detail

run

public TriadicCensus<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,TriadicCensus.Result>

Overrides:

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

Parameters:

input - input graph

Returns:

this

Throws:

Exception

getResult

public TriadicCensus.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
