* For example, if the {@link #obtain()} method calls {@code System.getenv("FOO")} then changes to
 * the {@code FOO} environment variable only invalidate the cache if the value returned by the
 * {@code obtain()} method itself changes. The same applies to reading files or system properties.
 * Starting an external process with a standard API (for example, {@code java.lang.ProcessBuilder}) is
 * also allowed.

To see all the options you have, checkout the docs for <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">Pydantic's exotic types</a>. You will see some examples in the next chapter.

For example, as in the `Image` model we have a `url` field, we can declare it to be an instance of Pydantic's `HttpUrl` instead of a `str`:

 * Some examples:
 * - For declarations: `@Deprecated("Should not be used") fun foo(){}`
 * - For types: `fun foo(x: List<@A Int>){}`
 * - Inside another annotation (`B` is annotation here): `@A(B()) fun foo(){}

### Examples

#### Egress Gateway

Deploying a Gateway to be used as an [Egress Gateway](https://istio.io/latest/docs/tasks/traffic-management/egress/egress-gateway/):

```yaml
service:

  // On Windows this method also replaces the alternate path separator '/' with
  // the primary path separator '\\', so that for example "bar\\/\\foo" becomes
  // "bar\\foo".

  void Normalize();

  // Returns a pointer to the last occurrence of a valid path separator in
  // the FilePath. On Windows, for example, both '/' and '\' are valid path
  // separators. Returns NULL if no path separator was found.

a subdirectory with the code of the error message, and add a `index.md` file that contains the
full description of the problem with potential remediation steps, examples, etc. See the existing
files in that directory for examples of how this is done.

With `Form` you can declare the same configurations as with `Body` (and `Query`, `Path`, `Cookie`), including validation, examples, an alias (e.g. `user-name` instead of `username`), etc.

!!! info
    `Form` is a class that inherits directly from `Body`.

!!! tip

It is compatible with:

* PostgreSQL
* MySQL
* SQLite

In this example, we'll use **SQLite**, because it uses a single file and Python has integrated support. So, you can copy this example and run it as is.

Later, for your production application, you might want to use a database server like **PostgreSQL**.
