Use `Objects.requireNonNull` statement or `Preconditions` rather than `assert` or `@SuppressWarning` annotation to suppress if possible.

For gradual adoption, enable checks project-by-project.
Do not rely on `@NullMarked` annotations.
Only enable checks for a project if all its dependencies have checks enabled, in order to avoid back-and-forth when refining the annotations.

## Use the instance as a dependency { #use-the-instance-as-a-dependency }

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")
```

correct. checkOnCurve(t, B) } func TestAddSubNegOnBaseP(t *testing.T) { checkLhs, checkRhs := &Point{}, &Point{} checkLhs.Add(B, B) tmpP2 := new(projP2).FromP3(B) tmpP1xP1 := new(projP1xP1).Double(tmpP2) checkRhs.fromP1xP1(tmpP1xP1) if checkLhs.Equal(checkRhs) != 1 { t.Error("B + B != [2]B") } checkOnCurve(t, checkLhs, checkRhs) checkLhs.Subtract(B, B) Bneg := new(Point).Negate(B) checkRhs.Add(B, Bneg) if checkLhs.Equal(checkRhs) != 1 { t.Error("B - B != B + (-B)") } if I.Equal(checkLhs) != 1 { t.Error("B...

      // Allowed in case test doesn't have privs
    }
  }

  /**
   * Checks that thread does not terminate within the default millisecond delay of {@code
   * timeoutMillis()}.
   */
  void assertThreadStaysAlive(Thread thread) throws InterruptedException {
    assertThreadStaysAlive(thread, timeoutMillis());
  }

  /** Checks that thread does not terminate within the given millisecond delay. */

# only on affected targets, usually. There are targets in //tensorflow/lite that
# don't pass --nobuild, so they're on their own.
#
# Although buildifier checks for formatting as well, "bazel build nobuild"
# checks for cross-file issues like bad includes or missing BUILD definitions.

# We can't test on the windows toolchains because they're using a legacy

## Используем экземпляр как зависимость { #use-the-instance-as-a-dependency }

Затем мы можем использовать этот `checker` в `Depends(checker)` вместо `Depends(FixedContentQueryChecker)`, потому что зависимостью является экземпляр `checker`, а не сам класс.

И при разрешении зависимости **FastAPI** вызовет `checker` примерно так:

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

    def __call__(self, q: str = ""):
        if q:
            return self.fixed_content in q
        return False


checker = FixedContentQueryChecker("bar")


@app.get("/query-checker/")
async def read_query_check(fixed_content_included: bool = Depends(checker)):

    }

    private void add(@Nullable Object[] elements, int n) {
      ensureRoomFor(n);
      /*
       * The following call is not statically checked, since arraycopy accepts plain Object for its
       * parameters. If it were statically checked, the checker would still be OK with it, since
       * we're copying into a `contents` array whose type allows it to contain nulls. Still, it's

These custom validators are for things that can be checked with **only** the **same data** provided in the request.

### Understand that Code { #understand-that-code }

## Utilize a instância como dependência { #use-the-instance-as-a-dependency }

Então, nós podemos utilizar este `checker` em um `Depends(checker)`, no lugar de `Depends(FixedContentQueryChecker)`, porque a dependência é a instância, `checker`, e não a própria classe.

E quando a dependência for resolvida, o **FastAPI** chamará este `checker` como:

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