org.apache.mahout.cf.taste.common.Refreshable

Implementations of this interface have state that can be periodically refreshed. For example, an implementation instance might contain some pre-computed information that should be periodically refreshed. The {@link #refresh(Collection)} method triggers such a refresh.

All Taste components implement this. In particular, {@link org.apache.mahout.cf.taste.recommender.Recommender}s do. Callers may want to call {@link #refresh(Collection)} periodically to re-compute information throughout the systemand bring it up to date, though this operation may be expensive.

public final class RefreshHelperTest extends TasteTestCase {


  @Test
  public void testCallable() {
    MockRefreshable mock = new MockRefreshable();
    Refreshable helper = new RefreshHelper(mock);
    helper.refresh(null);
    assertEquals(1, mock.getCallCount());
  }

    assertEquals(1, mock.getCallCount());
  }


  @Test
  public void testNoCallable() {
    Refreshable helper = new RefreshHelper(null);
    helper.refresh(null);
  }
