public TriangleListing()

Method Detail

getShortDescription

public String getShortDescription()

Description copied from interface: Driver

A one-line description, presented in the algorithm listing.

Returns:

short description

getLongDescription

public String getLongDescription()

Description copied from interface: Driver

A multi-line description, presented in the algorithm usage.

Returns:

long description

plan

public org.apache.flink.api.java.DataSet plan(org.apache.flink.graph.Graph<K,VV,EV> graph)
                                       throws Exception

Description copied from interface: Driver

"Run" algorithms and analytics on the input graph. The execution plan is not finalized here but in the output methods.

Drivers are first configured, next planned, and finally the chosen output method is called.

A null value should be returned when the Driver does not execute a GraphAlgorithm but only executes a GraphAnalytic.

Parameters:

graph - input graph

Throws:

Exception - on error

printAnalytics

public void printAnalytics(PrintStream out)

Description copied from interface: Driver

Analytic results are summaries so are always printed to the console irrespective of the chosen Output.

Specified by:

printAnalytics in interface Driver<K extends Comparable<K> & org.apache.flink.types.CopyableValue<K>,VV,EV>

Overrides:

printAnalytics in class DriverBase<K extends Comparable<K> & org.apache.flink.types.CopyableValue<K>,VV,EV>

Parameters:

out - output stream for printing results
