Hello, thanks, yes assumptions correct.|
Reading standard couple of times I get the same feeling but this is what I don't understand (may be too young on OSGi and Services) and I hope you(or anybody) can help me grasp.
If the Interface (Interface I) were describing a Dictionary Service and Service A was the English implementation and Service B The French implementation, if I had a bug or wanted to update the English version of the dictionary I would like to be able to bind the new Service A first and unbind the old. Little count that Service B is still there untouched (as it serves a different service).
In my example I want the Consume (Service C for instance) to decide and invoke either Service A or Service B based on Properties for example and if Service A (or B) goes away I would like to have a chance to detect the update and replace the Service before the old goes away.
Does this make sense ? Is it possible with the framework ?
