Examples with AbstractKeyedStateBackend org.apache.flink.runtime.state.AbstractKeyedStateBackend used on opensource projects

Example 1 with AbstractKeyedStateBackend

use of org.apache.flink.runtime.state.AbstractKeyedStateBackend in project flink by apache.

the class StreamingRuntimeContextTest method createListPlainMockOp.

@SuppressWarnings("unchecked")
private static AbstractStreamOperator<?> createListPlainMockOp() throws Exception {
    AbstractStreamOperator<?> operatorMock = mock(AbstractStreamOperator.class);
    ExecutionConfig config = new ExecutionConfig();
    KeyedStateBackend keyedStateBackend = mock(KeyedStateBackend.class);
    DefaultKeyedStateStore keyedStateStore = new DefaultKeyedStateStore(keyedStateBackend, config);
    when(operatorMock.getExecutionConfig()).thenReturn(config);
    doAnswer(new Answer<ListState<String>>() {

        @Override
        public ListState<String> answer(InvocationOnMock invocationOnMock) throws Throwable {
            ListStateDescriptor<String> descr = (ListStateDescriptor<String>) invocationOnMock.getArguments()[2];
            AbstractKeyedStateBackend<Integer> backend = new MemoryStateBackend().createKeyedStateBackend(new DummyEnvironment("test_task", 1, 0), new JobID(), "test_op", IntSerializer.INSTANCE, 1, new KeyGroupRange(0, 0), new KvStateRegistry().createTaskRegistry(new JobID(), new JobVertexID()));
            backend.setCurrentKey(0);
            return backend.getPartitionedState(VoidNamespace.INSTANCE, VoidNamespaceSerializer.INSTANCE, descr);
        }
    }).when(keyedStateBackend).getPartitionedState(Matchers.any(), any(TypeSerializer.class), any(ListStateDescriptor.class));
    when(operatorMock.getKeyedStateStore()).thenReturn(keyedStateStore);
    return operatorMock;
}

Example 2 with AbstractKeyedStateBackend

use of org.apache.flink.runtime.state.AbstractKeyedStateBackend in project flink by apache.

the class AbstractStreamOperator method setCurrentKey.

@SuppressWarnings({ "unchecked", "rawtypes" })
public void setCurrentKey(Object key) {
    if (keyedStateBackend != null) {
        try {
            // need to work around type restrictions
            @SuppressWarnings("unchecked,rawtypes") AbstractKeyedStateBackend rawBackend = (AbstractKeyedStateBackend) keyedStateBackend;
            rawBackend.setCurrentKey(key);
        } catch (Exception e) {
            throw new RuntimeException("Exception occurred while setting the current key context.", e);
        }
    }
}
