Modifier and Type	Method and Description
`void`	`lucyEnvStatusChanged(TLcyLucyEnvEvent aEvent)` Indicates that the status of the `ILcyLucyEnv` has changed.
`static ILcyLucyEnvListener`	`onceWhenClosed(Consumer<ILcyLucyEnv> aLucyEnvConsumer)` Utility method to create a new `ILcyLucyEnvListener` which will trigger `aLucyEnvConsumer` when the state of Lucy changes to `TLcyLucyEnvEvent.CLOSED`.
`static ILcyLucyEnvListener`	`onceWhenInitialized(Consumer<ILcyLucyEnv> aLucyEnvConsumer)` Utility method to create a new `ILcyLucyEnvListener` which will trigger `aLucyEnvConsumer` when the state of Lucy changes to `TLcyLucyEnvEvent.INITIALIZED`.

  - lucyEnvStatusChanged
```
void lucyEnvStatusChanged(TLcyLucyEnvEvent aEvent)
                   throws TLcyVetoException
```
    Indicates that the status of the ILcyLucyEnv has changed.
    
    Parameters:
    
    aEvent - The event describing the change.
    
    Throws:
    
    TLcyVetoException - The implementation of this listener can throw a TLcyVetoException when it wants to veto the change. These exceptions should only be thrown when Lucy switches from TLcyLucyEnvEvent.INITIALIZED to TLcyLucyEnvEvent.CLOSING.
    Throwing a TLcyVetoException for other state transitions might leave Lucy in an undefined state.
  - onceWhenInitialized
```
static ILcyLucyEnvListener onceWhenInitialized(Consumer<ILcyLucyEnv> aLucyEnvConsumer)
```
    Utility method to create a new ILcyLucyEnvListener which will trigger aLucyEnvConsumer when the state of Lucy changes to TLcyLucyEnvEvent.INITIALIZED.
    The created listener will only be triggered once. Once the listener has been triggered, it will de-register itself.
    
    Parameters:
    
    aLucyEnvConsumer - The consumer of the Lucy env
    
    Returns:
    
    a new ILcyLucyEnvListener

  - onceWhenClosed
```
static ILcyLucyEnvListener onceWhenClosed(Consumer<ILcyLucyEnv> aLucyEnvConsumer)
```
    Utility method to create a new ILcyLucyEnvListener which will trigger aLucyEnvConsumer when the state of Lucy changes to TLcyLucyEnvEvent.CLOSED.
    The created listener will only be triggered once. Once the listener has been triggered, it will de-register itself.
    
    Parameters:
    
    aLucyEnvConsumer - The consumer of the Lucy env
    
    Returns:
    
    a new ILcyLucyEnvListener
