Then, we could use this `checker` in a `Depends(checker)`, instead of `Depends(FixedContentQueryChecker)`, because the dependency is the instance, `checker`, not the class itself.

And when solving the dependency, **FastAPI** will call this `checker` like:

```Python
checker(q="somequery")
```

        }

        if (domain == null) {
            return null;
        }

        domain = domain.toLowerCase();

        if (log.isTraceEnabled()) {
            log.trace(String.format("Resolving \\%s\\%s%s", domain, root, path != null ? path : ""));
        }

        DfsReferralDataInternal dr = null;
        final long now = System.currentTimeMillis();
        synchronized (this.domainsLock) {

        interpolator.interpolateModel(model, null, request, collector);

        assertCollectorState(0, 1, 0, collector);
        assertEquals(
                "Resolving expression: '${basedir}': Detected the following recursive expression cycle in 'basedir': [basedir]",
                collector.getErrors().get(0));

* A PR should have a specific use case that it is solving.

* If the PR is for a feature, it should have docs.
    * Unless it's a feature we want to discourage, like support for a corner case that we don't want users to use.

You can define dependencies that in turn can define dependencies themselves.

In the end, a hierarchical tree of dependencies is built, and the **Dependency Injection** system takes care of solving all these dependencies for you (and their sub-dependencies) and providing (injecting) the results at each step.

For example, let's say you have 4 API endpoints (*path operations*):

* `/items/public/`

  /** Resolver for resolving parameter and field types with {@link #runtimeType} as context. */
  @LazyInit private transient @Nullable TypeResolver invariantTypeResolver;

  /** Resolver for resolving covariant types with {@link #runtimeType} as context. */
  @LazyInit private transient @Nullable TypeResolver covariantTypeResolver;
