Detailed Description

FunctionSorter allows user to define the designated 'compare' method and it will be evaluated to sort the data. The method takes two arguments (lhs and rhs) of the specified parameter type and the data can be accessed as below for evaluation,

 SortFilterProxyModel {
     sourceModel: model
     sorters: [
         FunctionSorter {
             id: functionSorter
             component RoleData: QtObject {
                 property real age
             }
             function compare(lhsData: RoleData, rhsData: RoleData) : int {
                 return (lhsData.age < rhsData.age) ? -1 : ((lhsData === rhsData.age) ? 0 : 1)
             }
         }
     ]
