### Question:
JPAEdmEntityContainer extends JPAEdmBaseViewImpl implements JPAEdmEntityContainerView { @Override public void clean() { super.clean(); entitySetView = null; associationSetView = null; currentEntityContainer = null; consistentEntityContainerList = null; } JPAEdmEntityContainer(final JPAEdmSchemaView view); @Override JPAEdmBuilder getBuilder(); @Override EntityContainer getEdmEntityContainer(); @Override List<EntityContainer> getConsistentEdmEntityContainerList(); @Override JPAEdmEntitySetView getJPAEdmEntitySetView(); @Override JPAEdmAssociationSetView getEdmAssociationSetView(); @Override void clean();  }### Answer:
@Test public void testIsConsistent() { assertTrue(objJPAEdmEntityContainer.isConsistent()); objJPAEdmEntityContainer.clean(); assertFalse(objJPAEdmEntityContainer.isConsistent()); }
