public void setParent(ServerConnector parent)

    Description copied from interface: ServerConnector
    
    Sets the parent for this connector. This method should only be called by the framework to ensure that the connector hierarchy on the client side and the server side are in sync.
    Note that calling this method does not fire a ConnectorHierarchyChangeEvent. The event is fired only when the whole hierarchy has been updated.
    
    Specified by:
    
    setParent in interface ServerConnector
    
    Overrides:
    
    setParent in class AbstractConnector
    
    Parameters:
    
    parent - The new parent of the connector
  - extend
```
protected abstract void extend(ServerConnector target)
```
    Called when the extension is attached to its parent. This method is only called once as an extension cannot be moved from one parent to another.
    
    Parameters:
    
    target - The connector this extension extends
