The MaxAggregator class implements the maximum aggregator. The maximum aggregator returns the maximum value of all measures. Flex uses this aggregator when you set the OLAPMeasure.aggregator property to "MAX".

Method Detail

computeBegin

()method
public function computeBegin(dataField:String):Object

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Flex calls this method to start the computation of an aggregation value.

Parameters

dataField:String — The name of the OLAPMeasure.dataField property for the measure to be aggregated.

Returns
Object — An Object initialized for the aggregation. Use this Object to hold any information necessary to perform the aggregation. You pass this Object to subsequent calls to the computeLoop() and computeEnd() methods.

computeEnd

()method 
public function computeEnd(data:Object, dataField:String):Number

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Flex calls this method to end the computation of the aggregation value.

Parameters

data:Object — The Object returned by the call to the computeLoop() method. Use this Object to hold information necessary to perform the aggregation.
 
dataField:String — The name of the OLAPMeasure.dataField property for the measure to be aggregated.

Returns
Number — The aggregated value.

computeLoop

()method 
public function computeLoop(data:Object, dataField:String, rowData:Object):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Flex calls this method when a new value needs to be added to the aggregation.

Parameters

data:Object — The Object returned by the call to the computeBegin() method, or calculated by a previous call to the computeLoop() method. Use this Object to hold information necessary to perform the aggregation. This method modifies this Object; it does not return a value.
 
dataField:String — The name of the OLAPMeasure.dataField property for the measure to be aggregated.
 
rowData:Object — The object representing the rows data that is being analyzed.

computeObjectBegin

()method 
public function computeObjectBegin(value:Object):Object

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Flex calls this method to start aggregation of aggregated values. Calculating the average value of a group of averages is an example of an aggregation of aggregated values.

Parameters

value:Object — The Object returned by the call to the computeEnd() method for a previous aggregation. Use this Object to hold the information necessary to perform the aggregation.

Returns
Object — An Object initialized for the aggregation. Use this Object to hold any information necessary to perform the aggregation. You pass this Object to subsequent calls to the computeObjectLoop() and computeObjectEnd() methods.

computeObjectEnd

()method 
public function computeObjectEnd(oldValue:Object, dataField:String):Number

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Flex calls this method to end the computation.

Parameters

oldValue:Object — The Object returned by a call to the computeObjectLoop() method that is used to store the aggregation results. This method modifies this Object; it does not return a value.
 
dataField:String — The name of the OLAPMeasure.dataField property for the measure to be aggregated.

Returns
Number — The aggregated value.

computeObjectLoop

()method 
public function computeObjectLoop(oldValue:Object, newValue:Object):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Flex calls this method when a new aggregated value needs to be added to the aggregation.

Parameters

oldValue:Object — The Object returned by a call the computeObjectBegin() method, or calculated by a previous call to the computeObjectLoop() method. This method modifies this Object; it does not return a value.
 
newValue:Object — The Object returned by the call to the computeEnd() method for a previous aggregation.
