 | 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. | EventDispatcher | |

Dispatches an event into the event flow. | EventDispatcher | |
evaluateExpression(expression:String, expressionDefinitionId:String, varsMap:Object, qualifiedClassName:String):Object
This API is used to evaluate an expression at flex side. | ExpressionEvaluationService | ||
|
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | EventDispatcher | |
|
Indicates whether an object has a specified property defined. | Object | |
|
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | |
|
Indicates whether the specified property exists and is enumerable. | Object | |

Method Detail
evaluateExpression | () | method |
public function evaluateExpression(expression:String, expressionDefinitionId:String, varsMap:Object, qualifiedClassName:String):Object| Language Version: | ActionScript 3.0 |
| Product Version: | Expression Manager Building Block 9.5 |
| Runtime Versions: | Flash Player 10.2, AIR (unsupported) |
This API is used to evaluate an expression at flex side. Throws ExpressionEvaluationError in case Swf load is not complete or errored out.
Parameters
expression:String — expression to be evaluated.
| |
expressionDefinitionId:String — unique id used to load the expression swf into flex application.
| |
varsMap:Object — map containing variables used in expressions.
| |
qualifiedClassName:String — Name of the AS class containing expressions. This name is passed to the generateSWF API at the time of generating swf.
|
Object — evaluated value of the expression.
|
registerExpressionsUsingBytesLoader | () | method |
public function registerExpressionsUsingBytesLoader(expressionDefinitionId:String, swfBytes:ByteArray, lazyLoad:Boolean = false):void| Language Version: | ActionScript 3.0 |
| Product Version: | Expression Manager Building Block 9.5 |
| Runtime Versions: | Flash Player 10.2, AIR (unsupported) |
Used to load swf from the specified byte array.
Parameters
expressionDefinitionId:String — unique id used later for evaluating expressions contained in this swf.
| |
swfBytes:ByteArray — byte[] containing swf.
| |
lazyLoad:Boolean (default = false) |
registerExpressionsUsingLoader | () | method |
public function registerExpressionsUsingLoader(expressionDefinitionId:String, expressionLoader:IExpressionLoader, lazyLoad:Boolean = false):void| Language Version: | ActionScript 3.0 |
| Product Version: | Expression Manager Building Block 9.5 |
| Runtime Versions: | Flash Player 10.2, AIR (unsupported) |
Used to load swf using a custom loader. The custom loader is required to implement IExpressionLoader.
Parameters
expressionDefinitionId:String — unique id used later for evaluating expressions contained in this swf.
| |
expressionLoader:IExpressionLoader — custom expression loader for loading swf.
| |
lazyLoad:Boolean (default = false) |
registerExpressionsUsingUrlLoader | () | method |

| Runtime Versions: | Flash Player 10.2, AIR (unsupported) |
Used to load the expression swf from the specified URL. urlVars can be used to specify URL parameters.
The swf is registered with the specified expressionDefinitionId. This id is required to be passed at the time of evaluating expressions.
Parameters
expressionDefinitionId:String — unique id used later for evaluating expressions contained in this swf.
| |
swfUrl:String — url of the swf.
| |
urlVars:Object (default = null) | |
lazyLoad:Boolean (default = false) |
