                    if param.get("required")
                }
                # Make sure required definitions of the same parameter take precedence
                # over non-required definitions
                all_parameters.update(required_parameters)

But we want to be able to parameterize that fixed content.

## A "callable" instance { #a-callable-instance }

In Python there's a way to make an instance of a class a "callable".

Not the class itself (which is already a callable), but an instance of that class.

To do that, we declare a method `__call__`:

	if accessKey == "" || gotSignature == "" || expires == "" {
		return ErrInvalidQueryParams
	}

	cred, _, s3Err := checkKeyValid(r, accessKey)
	if s3Err != ErrNone {
		return s3Err
	}

	// Make sure the request has not expired.
	expiresInt, err := strconv.ParseInt(expires, 10, 64)
	if err != nil {
		return ErrMalformedExpires
	}

	// Check if the presigned URL has expired.

2. Configure audit logging in MinIO with for example:

```
mc admin config set myminio audit_webhook enable=on endpoint=http://localhost:8080
```

		for i := len(orderBy.Columns) - 1; i >= 0; i-- {
			if orderBy.Columns[i].Reorder {
				orderBy.Columns = orderBy.Columns[i:]
				clause.Expression = orderBy
				return
			}
		}

		copiedColumns := make([]OrderByColumn, len(v.Columns))
		copy(copiedColumns, v.Columns)
		orderBy.Columns = append(copiedColumns, orderBy.Columns...)
	}

	clause.Expression = orderBy

     * Given that we declare this method as accepting and returning non-nullable values (because we
     * implement Function<A, B>, as discussed in a class-level comment), it would make some sense to
     * perform runtime null checks on the input and output. (That would also make NullPointerTester
     * happy!) However, since we didn't do that for many years, we're not about to start now.
