Check feasibility when time limit is reached

I have T seconds to solve an MIP problem. When the time limit T is reached, Gurobi could have found a feasible solution or failed to find one. In both cases, the status of the model becomes GRB.Status.TIME_LIMIT.

How do I know that if any feasible solutions found within the time limit?

One way could be trying gRBVar.X, where if an exception is thrown then you would know no feasible solutions could be found. But there must be a better way, right?

  I think I found an answer for this. Using gurobi.SolCount does the job.
