#### How relative imports work

/// tip

If you know perfectly how imports work, continue to the next section below.

///

A single dot `.`, like in:

```Python
from .dependencies import get_token_header
```

would mean:

                @Override
                public @Nullable Void call() throws Exception {
                  barrier.await();
                  Integer first = graph.nodes().iterator().next();
                  for (Integer node : graph.nodes()) {
                    Set<Integer> unused = graph.successors(node);
                  }
                  /*

		case "current":
			z.current, bts, err = msgp.ReadUint64Bytes(bts)
			if err != nil {
				err = msgp.WrapError(err, "current")
				return
			}
		case "next":
			z.next, bts, err = msgp.ReadUint64Bytes(bts)
			if err != nil {
				err = msgp.WrapError(err, "next")
				return
			}
		case "started":
			z.started, bts, err = msgp.ReadTimeBytes(bts)
			if err != nil {
				err = msgp.WrapError(err, "started")

But it's signed. So, when you receive a token that you emitted, you can verify that you actually emitted it.

That way, you can create a token with an expiration of, let's say, 1 week. And then when the user comes back the next day with the token, you know that user is still logged in to your system.

  public void testIn_compilesWithExplicitSupertype() {
    Collection<Number> nums = ImmutableSet.of();
    Predicate<Number> p1 = Predicates.in(nums);
    Predicate<Object> p2 = Predicates.<Object>in(nums);
    // The next two lines are not expected to compile.
    // Predicate<Integer> p3 = Predicates.in(nums);
    // Predicate<Integer> p4 = Predicates.<Integer>in(nums);
  }

Note: `Full` only refers to whether a `PushContext` recomputation is needed. Even within a `Full` push, we keep track of which configuration updates triggered this, so we could have "Full update of Config X" or "Full update of all configs".
