```
public abstract class BaseViewModel<VS extends ViewState>
extends ViewModel implements DefaultLifecycleObserver
                    
```
Base class representing ViewModel. It allows to observe LiveDatas, which is useful for observing ViewState. Observers are automatically removed when ViewModel is no longer used and will be destroyed. Beside that, it handles one-shot Events send from ViewModel to Activity/Fragment.

  - sendEvent
```
 final Unit sendEvent(Event<VS> event)
```
    Send one-shot event to internal bus and notify all of its observers
    
    Parameters:
    
    event - event to be sent
  - observeWithoutOwner
```
 final <T extends Any> Unit observeWithoutOwner(LiveData<T> $self, Function1<T, Unit> callback)
```
    Observe LiveData without particular owner (Activity eg.). Observer is removed when ViewModel is destroyed.
    
    Parameters:
    
    callback - Lambda called when new value is dispatched to LiveData
  - observeWithoutOwner
```
 final <T extends Any> Unit observeWithoutOwner(DefaultValueLiveData<T> $self, Function1<T, Unit> callback)
```
    Observe DefaultValueLiveData without particular owner (Activity eg.). Observer is removed when ViewModel is destroyed.
    
    Parameters:
    
    callback - Lambda called when new value is dispatched to LiveData
  - observeWithoutOwner
```
 final <T extends Any> Unit observeWithoutOwner(DefaultValueMediatorLiveData<T> $self, Function1<T, Unit> callback)
```
    Observe DefaultValueMediatorLiveData without particular owner (Activity eg.). Observer is removed when ViewModel is destroyed.
    
    Parameters:
    
    callback - Lambda called when new value is dispatched to LiveData
  - observeEvent
```
 final Unit observeEvent(LifecycleOwner lifecycleOwner, KClass<out Event<VS>> eventClass, Function1<Event<VS>, Unit> observer)
```
    Observe one-shot Event defined by event class and run observer lambda whenever event is received. This event class must be associated with current Activity/Fragment ViewState.
    
    Parameters:
    
    lifecycleOwner - Particular lifecycle owner that should be used for observing events
    
    eventClass - Observed event class
    
    observer - Lambda called when one-shot event is received
