Although you use `Depends` in the parameters of your function the same way you use `Body`, `Query`, etc, `Depends` works a bit differently.

You only give `Depends` a single parameter.

This parameter must be something like a function.

You **don't call it** directly (don't add the parenthesis at the end), you just pass it as a parameter to `Depends()`.

### Create an `Enum` class { #create-an-enum-class }

Import `Enum` and create a sub-class that inherits from `str` and from `Enum`.

By inheriting from `str` the API docs will be able to know that the values must be of type `string` and will be able to render correctly.

Then create class attributes with fixed values, which will be the available valid values:

 * } finally {
 *   closer.close();
 * }
 * }
 *
 * <p>Note that this try-catch-finally block is not equivalent to a try-catch-finally block using
 * try-with-resources. To get the equivalent of that, you must wrap the above code in <i>another</i>
 * try block in order to catch any exception that may be thrown (including from the call to {@code
 * close()}).
 *
 * <p>This pattern ensures the following:
 *
 * <ul>

        if (logger.isDebugEnabled()) {
            final String commandStr = stream(commands).get(stream -> stream.map(s -> {
