/// tip

This is just standard Python, it's called a "type alias", it's actually not specific to **FastAPI**.

But because **FastAPI** is based on the Python standards, including `Annotated`, you can use this trick in your code. 😎

///

* Add documentation about handling [CORS (Cross-Origin Resource Sharing)](https://fastapi.tiangolo.com/tutorial/cors/). PR [#169](https://github.com/tiangolo/fastapi/pull/169).

* By default, encode by alias. This allows using Pydantic `alias` parameters working by default. PR [#168](https://github.com/tiangolo/fastapi/pull/168).

## 0.16.0

        for (PlexusConfiguration d : parameterConfigurations) {
            Parameter parameter = new Parameter();

            parameter.setName(extractName(d));

            parameter.setAlias(d.getChild("alias").getValue());

            parameter.setType(d.getChild("type").getValue());

            String required = d.getChild("required").getValue();

            parameter.setRequired(Boolean.parseBoolean(required));

Это стандартный синтаксис python и называется "type alias", это не особенность **FastAPI**.

Но потому что **FastAPI** базируется на стандартах Python,  включая `Annotated`, вы можете использовать этот трюк в вашем коде. 😎
