    listener - must not be null.
  - removeListener
```
void removeListener(Object listener)
```
    Removes a listener from the component.
    
    Parameters:
    
    listener - listener to remove. Must not be null.
    
    Throws:
    
    IllegalLifecycleStateException - may be thrown if the Listenable is stopped.

```
    Returns:
    
    a set of all listeners registered on this component.
