Is there a Way to add an Observer to the Unity Transform Component?

In a unity editor extension I want to be able to react to changes that are made on Unity elements like the
Transform Component of a GameObject through the unity editor like e.g. the transform’s inspector or gizmos.

Does Unity therefor offer any possibility like adding an observer or listener on a Unity Component?
Since I’m going to build a complex structure of GameObjects I want to avoid checking for changes manually in an update routine.

If this is impossible, what is the Unity Way for doing this?

Thanks in advance!

I have looked for something like that, too. Sadly there is no direct way to do this.
The best way I’ve found, was a custom editor with a handle tied to the transform. Then it’s possible to react to changes in the handle’s position.

Thanks for your reply. Because I want to observe all parameters of the transform(parent, rotation,scale … ) this trick won’t work for me.
Is there really no other option to checking for changes all the time??? It seems to me that this problem should have occurred in many other editor extensions before.
