Luego, podríamos usar este `checker` en un `Depends(checker)`, en lugar de `Depends(FixedContentQueryChecker)`, porque la dependencia es la instance, `checker`, no la clase en sí.

Y al resolver la dependencia, **FastAPI** llamará a este `checker` así:

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

Você pode definir dependências que por sua vez definem suas próprias dependências.

Por fim, uma árvore hierárquica de dependências é criada, e o sistema de **Injeção de Dependência** toma conta de resolver todas essas dependências (e as sub-dependências delas) para você, e provê (injeta) os resultados em cada passo.

Por exemplo, vamos supor que você possua 4 endpoints na sua API (*operações de rota*):

* `/items/public/`

	globalFSOSync bool

	globalProxyEndpoints []ProxyEndpoint

	globalInternodeTransport http.RoundTripper

	globalRemoteTargetTransport http.RoundTripper

	globalDNSCache = &dnscache.Resolver{
		Timeout: 5 * time.Second,
	}

	globalForwarder *handlers.Forwarder

	globalTierConfigMgr *TierConfigMgr

	globalConsoleSrv *consoleapi.Server

       * work under Android.
       *
       * (Clearing inheritableThreadLocals could still be useful independent of class unloading, but
       * that's a larger problem, which we don't attempt to solve anywhere else in Guava.)
       */
      return null;
    }
    try {
      Field inheritableThreadLocals = Thread.class.getDeclaredField("inheritableThreadLocals");
      inheritableThreadLocals.setAccessible(true);

   * thus a motivated caller may be able to expose the reference to another thread that would then
   * call cancel() and be unable to cancel the delegate.
   * There are a number of ways to solve this, none of which are very pretty, and it is currently
   * believed to be a purely theoretical problem (since the other actions should supply sufficient
   * write-barriers).
