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: | AIR 1.0, Flash Player 9, Flash Player 10 |
Evaluates an expression in a Flex application.
If the SWF file is not loaded or the evaluation generates an error, an ExpressionEvaluationError value is thrown.
Parameters
expression:String — The expression to evaluate.
| |
expressionDefinitionId:String — The unique ID that is used to load the expression SWF into a Flex application.
| |
varsMap:Object — The map that contains the variables used in expressions.
| |
qualifiedClassName:String — The name of the ActionScript class that contains expressions. This name is passed to the generateSWF class when the SWF is generated.
|
Object — The value of the expression after evaluation.
|
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: | AIR 1.0, Flash Player 9, Flash Player 10 |
Loads a SWF from the specified byte array.
Parameters
expressionDefinitionId:String — The unique identifier that is used to evaluate expressions contained in this SWF later.
| |
swfBytes:ByteArray — The byte[] that contains the SWF.
| |
lazyLoad:Boolean (default = false)true, the SWF is loaded when the first expression is evaluated.
|
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: | AIR 1.0, Flash Player 9, Flash Player 10 |
Loads a SWF using a custom loader. The custom loader is required to implement IExpressionLoader.
Parameters
expressionDefinitionId:String — The unique identifier that is used for evaluating expressions contained in this SWF later.
| |
expressionLoader:IExpressionLoader — The custom expression loader that is used to load a SWF.
| |
lazyLoad:Boolean (default = false)true, the SWF is loaded when the first expression is evaluated.
|
registerExpressionsUsingUrlLoader | () | method |
public function registerExpressionsUsingUrlLoader(expressionDefinitionId:String, swfUrl:String, urlVars:Object = null, lazyLoad:Boolean = false):void| Language Version: | ActionScript 3.0 |
| Product Version: | Expression Manager Building Block 9.5 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Player 10 |
Loads the expression SWF from the specified URL. urlVars can be used to specify URL parameters.
The SWF is registered with the specified expressionDefinitionId. Passing this identifier is required when evaluating expressions.
Parameters
expressionDefinitionId:String — The unique identifier that is used to evaluate expressions contained in this SWF later.
| |
swfUrl:String — The URL of the SWF.
| |
urlVars:Object (default = null) | |
lazyLoad:Boolean (default = false)true, the SWF is loaded when the first expression is evaluated.
