Examples with LongValueToStringValue org.apache.flink.graph.asm.translate.translators.LongValueToStringValue used on opensource projects

Example 1 with LongValueToStringValue

use of org.apache.flink.graph.asm.translate.translators.LongValueToStringValue in project flink by apache.

the class TranslateTest method testTranslateGraphIds.

@Test
public void testTranslateGraphIds() throws Exception {
    Graph<StringValue, LongValue, LongValue> stringIdGraph = graph.translateGraphIds(new LongValueToStringValue());
    for (Vertex<StringValue, LongValue> vertex : stringIdGraph.getVertices().collect()) {
        assertEquals(StringValue.class, vertex.f0.getClass());
        assertEquals(LongValue.class, vertex.f1.getClass());
    }
    for (Edge<StringValue, LongValue> edge : stringIdGraph.getEdges().collect()) {
        assertEquals(StringValue.class, edge.f0.getClass());
        assertEquals(StringValue.class, edge.f1.getClass());
        assertEquals(LongValue.class, edge.f2.getClass());
    }
    TestBaseUtils.compareResultAsText(stringIdGraph.getVertices().collect(), expectedVertexResult);
