Example 6 with DefaultDelayOperator

use of com.datatorrent.common.util.DefaultDelayOperator in project apex-core by apache.

the class DelayOperatorTest method testFibonacciRecovery1.

@Test(timeout = 60000)
public void testFibonacciRecovery1() throws Exception {
    LogicalPlan dag = StramTestSupport.createDAG(testMeta);
    TestGeneratorInputOperator dummyInput = dag.addOperator("DUMMY", TestGeneratorInputOperator.class);
    FailableFibonacciOperator fib = dag.addOperator("FIB", FailableFibonacciOperator.class);
    DefaultDelayOperator opDelay = dag.addOperator("opDelay", DefaultDelayOperator.class);
