```kotlin
@JvmDefaultWithCompatibility
public interface MutableLongState : LongState, MutableState<Long>
```


A value holder where reads to the `longValue` property during the execution of a `Composable`
function cause the current `RecomposeScope` to subscribe to changes of that value. When the
`longValue` property is written to and changed, a recomposition of any subscribed
`RecomposeScope`s will be scheduled. If `longValue` is written to with the same value, no
recompositions will be scheduled.
