Detalhes do construtor
OLAPCube()Construtor
public function OLAPCube(name:String = null)

Constructor.

Parâmetros
name:String (default = null) — The name of the OLAP cube.
Detalhes do método
addEventListener()método
public function addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void

Registers an event listener object with an EventDispatcher object so that the listener receives notification of an event.

Parâmetros

type:String — The type of event.
 
listener:Function — The listener function that processes the event.
 
useCapture:Boolean (default = false) — Determines whether the listener works in the capture phase or the target and bubbling phases.
 
priority:int (default = 0) — The priority level of the event listener.
 
useWeakReference:Boolean (default = false) — Determines whether the reference to the listener is strong or weak. A strong reference (the default) prevents your listener from being garbage-collected. A weak reference does not.

cancelRefresh()método 
public function cancelRefresh():void

Aborts the current cube refresh, if one is executing.

dispatchEvent()método 
public function dispatchEvent(event:Event):Boolean

Dispatches an event into the event flow. The event target is the object upon which the dispatchEvent() method is called.

Parâmetros

event:Event — The Event object that is dispatched into the event flow.

Retorna
Boolean — A value of true if the event was successfully dispatched. A value of false indicates failure or that the preventDefault() method was called on the event.

execute()método 
public function execute(query:IOLAPQuery):AsyncToken

Queues an OLAP query for execution. After you call the refresh() method to update the cube, you must wait for a complete event before you call the execute() method.

OLAP cubes can be complex, so you do not want your application to pause while Flex calculates the results of your OLAP query. The execute() method returns an instance of the AsyncToken class, which lets you set up handlers for asynchronous operations so that your application can continue to execute during query processing.

When using the AsyncToken class, you set up two functions to handle the query results. In this exemplo, the showResult() function handles the query results when the query succeeds, and the showFault() function handles any errors detected during query execution:

      <mx:Script>
              
              // Function to execute a query.
              private function runQuery(cube:IOLAPCube):void {
                  // Create a query instance.
                  var query:IOLAPQuery = getQuery(cube);
                  // Execute the query.
                  var token:AsyncToken = cube.execute(query);
                  // Set up handlers for the query results.
                  token.addResponder(new AsyncResponder(showResult, showFault));
              }
              
              // Handle a query fault.
              private function showFault(result:Object, token:Object):void {
                  Alert.show("Error in query.");
              }
      
              // Handle a query success.
              private function showResult(result:Object, token:Object):void {
                  if (!result) {
                      Alert.show("No results from query.");
                      return;
                  }
      
                  myOLAPDG.dataProvider= result as OLAPResult;            
              }        
      </mx:Script>
      
      <mx:OLAPDataGrid id="myOLAPDG" width="100%" height="100%" />
      

Parâmetros

query:IOLAPQuery — The query to execute, represented by an IOLAPQuery instance.

Retorna
AsyncToken — An AsyncToken instance.
findDimension()método 
public function findDimension(name:String):IOLAPDimension

Returns the dimension with the given name within the OLAP cube.

Parâmetros

name:String — The name of the dimension.

Retorna
IOLAPDimension — An IOLAPDimension instance representing the dimension, or null if a dimension is not found.
hasEventListener()método 
public function hasEventListener(type:String):Boolean

Checks whether the object has any listeners registered for a specific type of event. This lets you determine where an object has altered handling of an event type in the event flow hierarchy.

Parâmetros

type:String — The type of event.

Retorna
Boolean — A value of true if a listener of the specified type is registered; false otherwise.

Veja também

refresh()método 
public function refresh():void

Refreshes the cube from the data provider. After setting the cube's schema, you must call this method to build the cube.

This method dispatches a progress event to indicate progress, and dispatches a complete event when the cube is complete and ready to execute queries. You must wait for a complete event before you call the execute() method to run a query.

removeEventListener()método 
public function removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void

Removes a listener. If there no matching listener is registered, a call to this method has no effect.

Parâmetros

type:String — The type of event.
 
listener:Function — The listener object to remove.
 
useCapture:Boolean (default = false) — Specifies whether the listener was registered for the capture phase or the target and bubbling phases.

Veja também

toString()método 
public function toString():String

Returns the name of the cube

Retorna
String — The name of the cube.
willTrigger()método 
public function willTrigger(type:String):Boolean

Checks whether an event listener is registered with this object or any of its ancestors for the specified event type. This method returns true if an event listener is triggered during any phase of the event flow when an event of the specified type is dispatched to this object or to any of its descendants.

Parâmetros

type:String — The type of event.

Retorna
Boolean — A value of true if a listener of the specified type is triggered; false otherwise.
