| virtual tresult | addDependent (FUnknown *object, IDependent *dependent)=0 | 
| Install update notification for given object. | |
| virtual tresult | removeDependent (FUnknown *object, IDependent *dependent)=0 |

Host implements dependency handling for plugins.
Can be used between host-objects and the Plug-In or inside the Plug-In to handle internal updates!
| 
 | pure virtual | 
Install update notification for given object.
It is essential to remove all dependencies again using 'removeDependent'! Dependencies are not removed automatically when the 'object' is released!
| object | : interface to object that sends change notifications | 
| dependent | : interface through which the update is passed | 
| 
 | pure virtual | 
Remove a previously installed dependency.
Inform all dependents, that object has changed.
| object | is the object that has changed | 
| message | is a value of enum IDependent::ChangeMessage, usually IDependent::kChanged - can be a private message as well (only known to sender and dependent) | 
Same as triggerUpdates, but delivered in idle (usefull to collect updates).
