    public schedule schedule     {                 {             return (contractconsignee == null ? null : contractconsignee.schedule);         }         set         {             if (contractconsignee == null)             {                 contractconsignee = new contractconsignee(session);                 contractconsignee.assignments.add(this);             }             contractconsignee.schedule = value;         }     } 

someone else wrote code. trying solve bug in our system. i'm not familiar with:

 == null ? null : contractconsignee.schedule 

? : conditional operator.

if contractconsignee null, getter returns null; otherwise, return contractconsignee.schedule.
