Detection of conflicts before delivery (plain API)

Hi Community,

I am searching for a solution to detect conflicts before deliver them to some other stream/workspace. As it is shown in the eclipse GUI for incoming conflicting changes even before I accept it.
At the moment our delivery fails if there is a change in the target component which is not coming from the source.

We would like to distinguish between a conflicting change and a non conflicting change.

We are using the plain API for our plugin.

Greetings Paul
