Examples with Result org.apache.flink.graph.library.metric.directed.VertexMetrics.Result used on opensource projects

Example 1 with Result

use of org.apache.flink.graph.library.metric.directed.VertexMetrics.Result in project flink by apache.

the class VertexMetricsTest method testWithCompleteGraph.

@Test
public void testWithCompleteGraph() throws Exception {
    long expectedDegree = completeGraphVertexCount - 1;
    long expectedBidirectionalEdges = completeGraphVertexCount * expectedDegree / 2;
    long expectedMaximumTriplets = CombinatoricsUtils.binomialCoefficient((int) expectedDegree, 2);
    long expectedTriplets = completeGraphVertexCount * expectedMaximumTriplets;
    Result expectedResult = new Result(completeGraphVertexCount, 0, expectedBidirectionalEdges, expectedTriplets, expectedDegree, expectedDegree, expectedDegree, expectedMaximumTriplets);
    Result vertexMetrics = new VertexMetrics<LongValue, NullValue, NullValue>().run(completeGraph).execute();
    assertEquals(expectedResult, vertexMetrics);
    assertEquals(expectedDegree, vertexMetrics.getAverageDegree(), ACCURACY);
