public function computeBegin(dataField:String):Object
Wersja języka: | ActionScript 3.0 |
Wersja produktu: | Flex 3 |
Wersje środowiska wykonawczego: | Flash Player 9, AIR 1.1 |
Flex calls this method to start the computation of an aggregation value.
Parametry
dataField:String — The name of the OLAPMeasure.dataField property
for the measure to be aggregated.
|
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 | () | metoda |
public function computeEnd(data:Object, dataField:String):Number
Wersja języka: | ActionScript 3.0 |
Wersja produktu: | Flex 3 |
Wersje środowiska wykonawczego: | Flash Player 9, AIR 1.1 |
Flex calls this method to end the computation of the aggregation value.
Parametry
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.
|
Number — The aggregated value.
|

public function computeLoop(data:Object, dataField:String, rowData:Object):void
Wersja języka: | ActionScript 3.0 |
Wersja produktu: | Flex 3 |
Wersje środowiska wykonawczego: | Flash Player 9, AIR 1.1 |
Flex calls this method when a new value needs to be added to the aggregation.
Parametry
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.

public function computeObjectBegin(value:Object):Object
Wersja języka: | ActionScript 3.0 |
Wersja produktu: | Flex 3 |
Wersje środowiska wykonawczego: | 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.
Parametry
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.
|
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.

Flex calls this method to end the computation.
Parametry
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.
|
Number — The aggregated value.
|
