User supplied callback function that would be used to compare the data elements while sorting the data. By default the data members would be compared directly.

The field of the input data set that provides the data for this OLAPAttribute instance.

A callback function that returns the actual data for the attribute. Use this callback function to return computed data based on the actual data. For example, you can return the month name as a String from actual date that represents the month as a number. Or, you can calculate a value. For example, your input data contains the ages of people, such as 1, 4, 9, 10, 12, 15, or 20. Your callback function can return an age group that contains the age, as in 1-10, or 11-20.

The signature of the callback function is:

         function myDataFunction(rowData:Object, dataField:String):Object;

The function can return a String or a Number.

The following example returns the age group for each age value in the flat data:

         private function ageGroupingHandler(rowData:Object, field:String):Object
         {
             return rowData[field] / 10;
         } 

A callback function that returns the display name of a member element. Flex calls this function for each member added to the OLAPAttribute instance.

The function signature is:

          function myDisplayNameFunction(memberName:String):String

where memberName contains the name of the element.

The function returns the display name of the element.

The following example converts a numeric group name, such as 1,2, or 3 into display names "0-9", "10-19":

          private function myDispFunction(name:String):String
          {
              var value:int = parseInt(name);
              return String((value)0 + " - ") + String((value+1)0-1);     
          }

Contains true becasue attributes are assumed to be aggregatable and all member is present.

All members of all the levels that belong to this hierarchy, as a list of IOLAPMember instances. The returned list might represent remote data and therefore can throw an ItemPendingError.
