Example 1 with MockSplitEnumerator

use of org.apache.flink.connector.base.source.reader.mocks.MockSplitEnumerator in project flink by apache.

the class HybridSourceTest method testBuilderWithEnumeratorSuperclass.

@Test
public void testBuilderWithEnumeratorSuperclass() {
    HybridSource.SourceFactory<Integer, Source<Integer, ?, ?>, MockSplitEnumerator> sourceFactory = (HybridSource.SourceFactory<Integer, Source<Integer, ?, ?>, MockSplitEnumerator>) context -> {
        MockSplitEnumerator enumerator = context.getPreviousEnumerator();
        return new MockBaseSource(1, 1, Boundedness.BOUNDED);
    };
    HybridSource<Integer> source = new HybridSource.HybridSourceBuilder<Integer, MockSplitEnumerator>().<ExtendedMockSplitEnumerator, Source<Integer, ?, ?>>addSource(new MockBaseSource(1, 1, Boundedness.BOUNDED)).addSource(sourceFactory, Boundedness.BOUNDED).build();
    assertNotNull(source);
}

Example 2 with MockSplitEnumerator

use of org.apache.flink.connector.base.source.reader.mocks.MockSplitEnumerator in project flink by apache.

    setupEnumeratorAndTriggerSourceSwitch();
    enumerator = (HybridSourceSplitEnumerator) source.createEnumerator(context);
    enumerator.start();
    HybridSourceEnumeratorState enumeratorState = enumerator.snapshotState(0);
    MockSplitEnumerator underlyingEnumerator = getCurrentEnumerator(enumerator);
    Assert.assertThat((List<MockSourceSplit>) Whitebox.getInternalState(underlyingEnumerator, "splits"), Matchers.iterableWithSize(1));
    enumerator = (HybridSourceSplitEnumerator) source.restoreEnumerator(context, enumeratorState);
