Examples with Nothing org.apache.flink.types.Nothing used on opensource projects

Example 1 with Nothing

use of org.apache.flink.types.Nothing in project flink by apache.

the class GenericDataSinkBaseTest method testDataSourceWithRuntimeContext.

@Test
public void testDataSourceWithRuntimeContext() {
    try {
        TestRichOutputFormat out = new TestRichOutputFormat();
        GenericDataSinkBase<String> sink = new GenericDataSinkBase<String>(out, new UnaryOperatorInformation<String, Nothing>(BasicTypeInfo.STRING_TYPE_INFO, BasicTypeInfo.getInfoFor(Nothing.class)), "test_sink");
        sink.setInput(source);
        ExecutionConfig executionConfig = new ExecutionConfig();
        final HashMap<String, Accumulator<?, ?>> accumulatorMap = new HashMap<String, Accumulator<?, ?>>();
        final HashMap<String, Future<Path>> cpTasks = new HashMap<>();
        final TaskInfo taskInfo = new TaskInfo("test_sink", 1, 0, 1, 0);
        executionConfig.disableObjectReuse();
        in.reset();
        sink.executeOnCollections(asList(TestIOData.NAMES), new RuntimeUDFContext(taskInfo, null, executionConfig, cpTasks, accumulatorMap, new UnregisteredMetricsGroup()), executionConfig);
        assertEquals(out.output, asList(TestIOData.RICH_NAMES));
        executionConfig.enableObjectReuse();
        out.clear();
        in.reset();
        sink.executeOnCollections(asList(TestIOData.NAMES), new RuntimeUDFContext(taskInfo, null, executionConfig, cpTasks, accumulatorMap, new UnregisteredMetricsGroup()), executionConfig);
        assertEquals(out.output, asList(TestIOData.RICH_NAMES));
    } catch (Exception e) {
        e.printStackTrace();
        fail(e.getMessage());
    }
}

Example 2 with Nothing

use of org.apache.flink.types.Nothing in project flink by apache.

the class GenericDataSinkBaseTest method testDataSourcePlain.

@Test

    try {
        TestNonRichOutputFormat out = new TestNonRichOutputFormat();
        GenericDataSinkBase<String> sink = new GenericDataSinkBase<String>(out, new UnaryOperatorInformation<String, Nothing>(BasicTypeInfo.STRING_TYPE_INFO, BasicTypeInfo.getInfoFor(Nothing.class)), "test_sink");
        sink.setInput(source);
        ExecutionConfig executionConfig = new ExecutionConfig();
        executionConfig.disableObjectReuse();
        in.reset();
        sink.executeOnCollections(asList(TestIOData.NAMES), null, executionConfig);
        assertEquals(out.output, asList(TestIOData.NAMES));
        executionConfig.enableObjectReuse();
        out.clear();
        in.reset();
        sink.executeOnCollections(asList(TestIOData.NAMES), null, executionConfig);
        assertEquals(out.output, asList(TestIOData.NAMES));
    } catch (Exception e) {
        e.printStackTrace();
