构造函数

public function ExpressionEvaluationService(defaultSwfUrl:String, expressionDefinitionParamName:String)

语言版本:

ActionScript 3.0

产品版本:

Expression Manager Building Block 9.5

运行时版本:

Flash Player 10.2, AIR (unsupported)

Constructor of expression evaluation service.

参数

	`defaultSwfUrl:String` — URL of the SWF.

	`expressionDefinitionParamName:String` — parameter name used in SWF url.

方法详细信息

evaluateExpression

()

方法

 public function evaluateExpression(expression:String, expressionDefinitionId:String, varsMap:Object, qualifiedClassName:String):Object

语言版本:

ActionScript 3.0

产品版本:

Expression Manager Building Block 9.5

运行时版本:

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.

参数

	`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

()

方法

 public function registerExpressionsUsingBytesLoader(expressionDefinitionId:String, swfBytes:ByteArray, lazyLoad:Boolean = false):void

语言版本:

ActionScript 3.0

产品版本:

Expression Manager Building Block 9.5

运行时版本:

Flash Player 10.2, AIR (unsupported)

Used to load swf from the specified byte array.

参数

	`expressionDefinitionId:String` — unique id used later for evaluating expressions contained in this swf.

	`swfBytes:ByteArray` — byte[] containing swf.

	`lazyLoad:Boolean` (default = `false`) — if true swf will be loaded on first expression evaluation.

registerExpressionsUsingLoader

()

方法

 public function registerExpressionsUsingLoader(expressionDefinitionId:String, expressionLoader:IExpressionLoader, lazyLoad:Boolean = false):void

语言版本:

ActionScript 3.0

产品版本:

Expression Manager Building Block 9.5

运行时版本:

Flash Player 10.2, AIR (unsupported)

Used to load swf using a custom loader. The custom loader is required to implement IExpressionLoader.

参数

	`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`) — if true swf will be loaded on first expression evaluation.

registerExpressionsUsingUrlLoader

()

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.

参数

	`expressionDefinitionId:String` — unique id used later for evaluating expressions contained in this swf.

	`swfUrl:String` — url of the swf.

	`urlVars:Object` (default = `null`) — url variables

	`lazyLoad:Boolean` (default = `false`) — if true swf will be loaded on first expression evaluation.
