Optionalsession: MaybeRefOrGetter<GraffitiSession | null | undefined>object: A ref containing
the retrieved object, undefined while loading, or null if not found or the fetch fails.error: A ref containing the fetch error for failures other than not found,
or null otherwise.poll: A function that can be called to manually check if the object has changed.
If a poll is already running, it waits for that poll.
The Graffiti.get method as a reactive composable for use in the Vue composition API.
Its corresponding renderless component is GraffitiGet.
The arguments of this composable are the same as Graffiti.get, only they can also be Refs or getters. As they change the output will automatically update. Reactivity only triggers when the root array or object changes, not when the elements or properties change. If you need deep reactivity, wrap your argument in a getter.
