Like above, this is an immutable part of the identity of the domain object and cannot be changed.

### Properties in entirely new classes

When developing an entirely new class (task, extension, domain object, etc), the API should consist of managed lazy properties.

// of the source code corresponding to that address.

// This tool is intended for use only by pprof; its interface may change or
// it may be deleted entirely in future releases.

 * A class that can supply objects of a single type; a pre-Java-8 version of {@link
 * java.util.function.Supplier java.util.function.Supplier}. Semantically, this could be a factory,
 * generator, builder, closure, or something else entirely. No guarantees are implied by this
 * interface.

 * <p>The {@link Suppliers} class provides common suppliers and related utilities.

# Conditional OpenAPI

If you needed to, you could use settings and environment variables to configure OpenAPI conditionally depending on the environment, and even disable it entirely.

## About security, APIs, and docs

Hiding your documentation user interfaces in production *shouldn't* be the way to protect your API.

That doesn't add any extra security to your API, the *path operations* will still be available where they are.

    assertThat("Thursday, 01-Jan-1970 00:00:00 PST JUNK".toHttpDateOrNull()!!.time)
      .isEqualTo(28800000L)

    // ANSI C's asctime() format
    // This format ignores the timezone entirely even if it is present and uses GMT.
    assertThat("Fri Jun 6 12:30:30 2014 PST".toHttpDateOrNull()!!.time).isEqualTo(1402057830000L)

...this would work:

```JSON
{
    "item_id": "foo-item",
    "needy": "sooooneedy"
}
```

And of course, you can define some parameters as required, some as having a default value, and some entirely optional:

```Python hl_lines="8"
{!> ../../docs_src/query_params/tutorial006_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="10"
