ExpressionManagerImpl - Adobe ActionScript® 3 (AS3 Expression Manager) API 参考

包	com.adobe.solutions.exm.runtime.impl
类	public class ExpressionManagerImpl
继承	ExpressionManagerImpl Object
实现	IExpressionManager

语言版本:

ActionScript 3.0

产品版本:

Expression Manager Building Block 10

运行时版本:

AIR (unsupported), Flash Player 10.2

The default implementation of the ExpressionManager interface, which serves as the entry point into the Expression Manager runtime. An instance of this class must be configured with a variable resolver and function mapper in order to be able to manage expressions with variable references and function calls.

方法详细信息

assignTo

()

方法

public function assignTo(assignTo:String, expression:String):void

语言版本:

ActionScript 3.0

产品版本:

Expression Manager Building Block 10

运行时版本:

AIR (unsupported), Flash Player 10.2

Assigns the result of evaluation of the given expression to the given variable. The target variable is updated automatically whenever an expression recomputation event is triggered (e.g. due to a dependent variable change, etc.).

参数

	`assignTo:String` — The target variable to which the result of expression evaluation is assigned.

	`expression:String` — The expression to be evaluated.

manage

()

方法

public function manage(expression:String):IComputedExpression

语言版本:

ActionScript 3.0

产品版本:

Expression Manager Building Block 10

运行时版本:

AIR (unsupported), Flash Player 10.2

Returns a ComputedExpression instance for the given expression string, which applications can use for reading or binding to the result of evaluation of the expression.

参数

expression:String — An expression string.

IComputedExpression — A ComputedExpression instance for the given expression string.

manageExpression

()

方法

public function manageExpression(expression:IExpression):IComputedExpression

语言版本:

ActionScript 3.0

产品版本:

Expression Manager Building Block 10

运行时版本:

AIR (unsupported), Flash Player 10.2

Returns a ComputedExpression instance for the given expression, and if the 'assignTo' property of the given expression is set, automatically assigns the result of expression evaluation to the variable represented by this property.

参数

expression:IExpression — An expression object with the 'expression' property, and optionally the 'assignTo' property, set.

IComputedExpression — A ComputedExpression instance for the given expression.

manageList

()

方法

public function manageList(expressionsVector:Vector.<IExpression>):Vector.<IComputedExpression>

语言版本:

ActionScript 3.0

产品版本:

Expression Manager Building Block 10

运行时版本:

AIR (unsupported), Flash Player 10.2

Returns a list of ComputedExpression instances for the given list of expression objects.

参数

expressionsVector:Vector.<IExpression> — A list of Expression instances.

Vector.<IComputedExpression> — A list of ComputedExpression instances for the given list of expressions.
