## Classes

### `LabelDiver` <sup><a href="https://github.com/PrefectHQ/prefect/blob/main/src/prefect/events/schemas/labelling.py#L6" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

The LabelDiver supports templating use cases for any Labelled object, by
presenting the labels as a graph of objects that may be accessed by attribute.  For
example:

```python  theme={null}
diver = LabelDiver({
    'hello.world': 'foo',
    'hello.world.again': 'bar'
})

assert str(diver.hello.world) == 'foo'
assert str(diver.hello.world.again) == 'bar'
```
