Examples with EdgeValue org.apache.flink.graph.library.Summarization.EdgeValue used on opensource projects

Example 1 with EdgeValue

use of org.apache.flink.graph.library.Summarization.EdgeValue in project flink by apache.

the class SummarizationITCase method testWithVertexAndEdgeStringValues.

@Test
public void testWithVertexAndEdgeStringValues() throws Exception {
    ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
    Graph<Long, String, String> input = Graph.fromDataSet(SummarizationData.getVertices(env), SummarizationData.getEdges(env), env);
    List<Vertex<Long, Summarization.VertexValue<String>>> summarizedVertices = new ArrayList<>();
    List<Edge<Long, EdgeValue<String>>> summarizedEdges = new ArrayList<>();
    Graph<Long, Summarization.VertexValue<String>, EdgeValue<String>> output = input.run(new Summarization<>());
    output.getVertices().output(new LocalCollectionOutputFormat<>(summarizedVertices));
    output.getEdges().output(new LocalCollectionOutputFormat<>(summarizedEdges));
    env.execute();
    validateVertices(SummarizationData.EXPECTED_VERTICES, summarizedVertices);
    validateEdges(SummarizationData.EXPECTED_EDGES_WITH_VALUES, summarizedEdges);
}

Example 2 with EdgeValue

use of org.apache.flink.graph.library.Summarization.EdgeValue in project flink by apache.

the class SummarizationITCase method testWithVertexAndEdgeLongValues.

@Test
public void testWithVertexAndEdgeLongValues() throws Exception {
    ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
    Graph<Long, Long, Long> input = Graph.fromDataSet(SummarizationData.getVertices(env), SummarizationData.getEdges(env), env).run(new TranslateVertexValues<>(new StringToLong())).run(new TranslateEdgeValues<>(new StringToLong()));
    List<Vertex<Long, Summarization.VertexValue<Long>>> summarizedVertices = new ArrayList<>();
    List<Edge<Long, EdgeValue<Long>>> summarizedEdges = new ArrayList<>();
    Graph<Long, Summarization.VertexValue<Long>, EdgeValue<Long>> output = input.run(new Summarization<>());
    output.getVertices().output(new LocalCollectionOutputFormat<>(summarizedVertices));
    output.getEdges().output(new LocalCollectionOutputFormat<>(summarizedEdges));
    env.execute();
    validateVertices(SummarizationData.EXPECTED_VERTICES, summarizedVertices);
    validateEdges(SummarizationData.EXPECTED_EDGES_WITH_VALUES, summarizedEdges);
}

    env.execute();
    validateVertices(SummarizationData.EXPECTED_VERTICES, summarizedVertices);
    validateEdges(SummarizationData.EXPECTED_EDGES_ABSENT_VALUES, summarizedEdges);
