Description
I'm using the asynchronous java driver. I hope you can help me to solve the problem of the following scenario.
First, using the "find" operator I want to check if there is an entry in my collection. If yes, the callback will be called and I can use it. If there is no entry in my collection, my application should generate this value and persist it. But how could I recognize that "find" can't find any entry?
