* A command used by a resolver strategy to get class descriptors. A command may return none, a
* single class descriptor or multiple class descriptors and even if class descriptors are returned,
* is not garanteed that the requested descriptor is within. No exceptions are thrown if the class
* could not be resolved - this is a possible result! Commands are planned to be something like a
* service which might get invoked multiple times in parallel. So no resolve specific states are
* allowed to be stored in the class state!
