## Required query parameters { #required-query-parameters }

When you declare a default value for non-path parameters (for now, we have only seen query parameters), then it is not required.

If you don't want to add a specific value but just make it optional, set the default as `None`.

        LogStream.setInstance(testStream);

## Deeply nested models { #deeply-nested-models }

You can define arbitrarily deeply nested models:

	blockSize                int64
}
