建構函式

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

語言版本:

ActionScript 3.0

產品版本:

Expression Manager Building Block 9.5

執行階段版本:

Flash Player 10.2, AIR (unsupported)

Constructor of expression evaluation service.

參數

	`defaultSwfUrl:String` — URL of the SWF.

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

方法詳細資訊

evaluateExpression

()

方法

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

語言版本:

ActionScript 3.0

產品版本:

Expression Manager Building Block 9.5

執行階段版本:

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.

參數

	`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.

傳回值

Object — evaluated value of the expression.

registerExpressionsUsingBytesLoader

()

方法

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

語言版本:

ActionScript 3.0

產品版本:

Expression Manager Building Block 9.5

執行階段版本:

Flash Player 10.2, AIR (unsupported)

Used to load swf from the specified byte array.

參數

	`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
