IOLAPCube  - AS3 Flex

All dimensions in the cube, as a list of IOLAPDimension instances.

The name of the OLAP cube.

Aborts a query that has been submitted for execution.

Parámetros

Aborts the current cube refresh, if one is executing.

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 example, 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:FaultEvent, 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%" />

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

Parámetros

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.
