For better readability, seems better to be able to do `if (selection.type() == AssignorSelection.Type.CLIENT)` Regarding the constructors, having static factory methods here instead of constructors allows to have meaningful names, so clients using the AssignorSelection can explicitly indicate what they want to create (`newClientAssignors` or `newServerAssignor`). We only pass null internally to the private constructor so seemed like a fair price to pay internally in the class, in order to provide a very explicit way to create new instances. -- This is an automated message from the Apache Git Service.
