Example 1 with Limit

use of uk.gov.gchq.gaffer.operation.impl.Limit in project Gaffer by gchq.

the class CoreOperationChainOptimiserTest method shouldAddLimitOperationForGetOperationsWithLimit.

@Test
public void shouldAddLimitOperationForGetOperationsWithLimit() throws Exception {
    // Given
    final Store store = mock(Store.class);
    final CoreOperationChainOptimiser optimiser = new CoreOperationChainOptimiser(store);
    final GetIterableOperation getOperation = mock(GetIterableOperation.class);
    final OperationChain<Integer> opChain = new OperationChain<>(getOperation);
    final int resultLimit = 5;
    given(getOperation.getResultLimit()).willReturn(resultLimit);
    // When
    final OperationChain<Integer> optimisedOpChain = optimiser.optimise(opChain);
    // Then
    assertEquals(2, optimisedOpChain.getOperations().size());
    assertSame(getOperation, optimisedOpChain.getOperations().get(0));
    assertTrue(optimisedOpChain.getOperations().get(1) instanceof Limit);
    assertEquals(resultLimit, (int) ((Limit) optimisedOpChain.getOperations().get(1)).getResultLimit());
}
